Naomi Universal monitor in a Blast City

[jonny]

has anyone here done this? i have a terribly burnt stock blast city monitor with a dead chasis so i swapped in a stock monitor from a naomi universal. in order to mount properly i took the mounting brackets off of the stock blast monitor and put them onto the naomi monitor. all is well, and it drops right in.

my question is how to get the bezel to fit or if any other bezels can be used in place of the stock blast bezel. i don't think i can trim enough away to make it fit right.

[Mr-Megalo]

I assume you have used a hi res 31k Only Nanao MS29-32 ? why did you need to swap frames ?

only monitors that will fit with the original blast bezel is a Sanwa Tri Sync 29x21s, Sanwa 31ES, Nanao MS29-30 or Nanao MS29-31AUTO, this is because of the screen curvature, the MS9's and MS29-32 are more curved than the stock monitor, trimming the bezel wouldn't work AFAIK

you could fit a flat screen monitor in and have a slight gap

[jonny]

i swapped frames rather than drilling new holes since i couldn't get them to line up well enough. all i had to do on the old frames is make two slots for the chasis brackets.

i can mount the plates on the front of the monitor rather than the back and it will sink the monitor into the cab a little bit, maybe that will give me enough room. maybe i should just buy a flat screen.

BLAST! heh

[Mr-Megalo]

jonny, show me the frame of the naomi monitor please, i know the Blasts hang on the different holes than the Naomi cabs, but the frames should be the same, on the Sega monitors i've worked with the frames have had mounting holes for both Blasts and Naomi Universals, mabe the US cabs have different frames ?

yes you could try rear mounting the tube to the frame (I had to do this with a Windy 2 and a Pentranic monitor) and use a spacer, but just make sure theres enough room at the rear, you dont want to "neck" the tube if there isn't enough clearance space at the rear of the Blast

[jonny]

the frames are the same (naomi and blast) but the naomi frames didn't have holes for mounting in a blast. that's why i just swapped as it was much easier. actually the frames are *slightly* different, but not anything significant.

there is enough room at the back of the blast for this move as it isn't very much.

[Mr-Megalo]

thats strange, UK Naomi monitor frames have both sets of holes, i've got both the Sanwa 31es frames and the Nanao MS29-32 and both have the holes in for mounting in a Blast - still at least swapping the frames around for you wasn't hard as they are simple to do.

a favour please, let me know how you get on with the fitment of the replacement screen by rear mounting the CRT to the frame, would be interested to hear and see the results, I know it can be a problem if using a NON Sega monitor (IE a betson or makvision) some CRT mounts on some tubes are placed slightly further back.

funny as I was discussing something similar to this today with Craig @ Giz10p as we were discussing the bezel situation on UK Naomi cabs

[jonny]

i'll take some pics when i get back today to illustrate my problem. basically in rear-mounting the monitor i now have an issue with the horizontal parts of the brackets running into the mounting areas in the cabinet. i'm going to trim down the metal pieces on the cabinet to allow the monitor to drop in (as there is plenty of material that could be taken out) and then i'll see how the monitor fits in regards to the bezel.

once the monitor is in i can decide if i need to add spacers to drop the monitor back even further with out impeding on the cab/tube.

[N80G80]

Not to go off topic..but wouldnt a Wei ya chassis replacement be a hell of alot easier....Im sure Meg and the guys here know what model youd need!

[cools]

That wouldn't solve the burn-in.

[jonny]

Not to go off topic..but wouldnt a Wei ya chassis replacement be a hell of alot easier....Im sure Meg and the guys here know what model youd need!

at some point in time i may still score a wei-ya chasis and hook it up for a spare or to sell or if i can tolerate the burn-in, then to actually use it but as cools said, it doesn't solve the burn in and this naomi monitor is mint and i got it on the uber-cheap.

[jonny]

ok i ended up rear mounting the plates to the monitor and adding two washers to further recess the monitor. i had to trim the lower plates on the Blast City (shown below) in order for the monitor to fit in without banging the hell out of the cab. as it is now, the bezel still does not fit, but it is extremely close and i believe i can dremmel the bezel down just slightly and attain what i need. i am very happy with the results here.

[robivy64]

I wishi I could do that sort of thing

[Mr-Megalo]

hello robivy, welcome :smile:
you've finally posted :laugh:

[jonny]

how much are wei-ya chasis going for these days?

[jonny]

also, it seems like i've heard arguments for wei-ya's being shit as well as being great. i want to say the biggest complaint i heard was large scan lines on low res stuff, but i honestly don't remember and i hate searching other forums.

basically i have a nanao tri-sync with a dead chasis (flyback pissed out a bunch of brown goop onto the board).

[Mr-Megalo]

did you get your Blast from Stellarolla then ?

the wei ya scanline stuff is debatable, so heres my honest view on the matter

its ALL about the tube, the wei ya chassis's will either looks too scanline heavy in 15k on certain tubes or too soft on other tubes if you like the heavier scanlines.
with a Toshiba tube on say an MS9 (found in New Astro City, Egret 2 etc etc) the scanlines can look quite heavy in 15k, on a sanwa tube, they are quite soft.

there are some sync issues depending on how the chassis is installed aswell as what game is being used, but there are ways round this in some circumstances.

anyways, if you want to do the chassis replacement
http://www.arcade-game-sales.com/products/sega-blast/5372-1.html

or alternatively you could ask someone who does monitor repairs if they can source a replacement flyback as they could still be available

[jonny]

meg, i didn't get it directly from stellarolla, but i was at the house in which he delivered it to and the cab has since become mine.

a friend of mine in california has the same flyback issue as me and he's going to contact PNL about flybacks for both he and myself. hopefully i can work that out rather than doing a chasis swap.

[Mr-Megalo]

ah gotcha, I remember seeing bens pics of the chassis when it went tits up

[jonny]

yes it sits on my floor unchanged from the pics you've seen. i have no idea who to contact about flybacks what-so-ever.

i also didn't know if just cleaning up the brown goop and swapping flybacks would fix it.

i've got ben's cab looking pretty good now though, control box has quite a bit of bondo on one corner (resanded and repainted to look pretty good, 100x better than before), it was missing some parts (marquee stuff, doors, still missing CP lock bracket, coin box lock mech, etc), i had to fill a couple knife wounds above the left speaker and paint over those.

it's definetly a lower condition Blast City but i'm pretty happy with it and i did a lot of sourcing parts and minor restoring so it was a good project/learning exp.

the other Blast was Outrun2's from killercabs, Marcell i believe it was. i remember he gave Ben a lot of shit about his Blast. kinda funny i got both of their cabs now.

[jonny]

hey Meg, you mentioned a replacement chasis for a Blast City in this thread over at neogeo.com...

http://www.neo-geo.com/forums/showthread.php?t=179401

i'm trying to get califoreigner to set me up with that Blast City (good friend of mine) but i'd need to do a new chasis (as well as get a spare for my old unused monitor).

i know i've asked this before, but...is that chasis suitable? is the linked chasis the Wei-Ya? if not, is it better than the Wei-Ya?

[Mr-Megalo]

its one of the Wei Ya M31 series of chassis yes, but Cosmicco also sell a Rodotron model that can be used on some of the Blasts.
you would be best finding out the number on the tube and discussing it in more details either with the seller of the chassis in the link I provided, or contact jomac at jomac.net.au - I think Joey @ Jomac would probably sell the chassis too, or could at least obtain them as he is a bit of a monitor guru to say the least

the Blast califoreigner made on NG.com - his chassis was an MS29-31Auto, same as the one you had that leaked all the goop all over.

[jonny]

the Blast califoreigner made on NG.com - his chassis was an MS29-31Auto, same as the one you had that leaked all the goop all over.

this is one big reason i want califoreigner's Blast since he has the same issue with the same monitor. i'd like a reason to order a chasis for my original monitor so needing two chasis would be a good reason. if anything happens with it i'll follow up on your leads for chasis and who knows, you might even get a PM or two. :laugh:

chasis chasis chasis

[Mr-Megalo]

thats cool, you know where I am if you need me.

pay my air fare and i'll come fit them for you :laugh:

[Mr-Megalo]

Jonny - looks like i'm going to get one of these chassis myself for a Nanao tube
another victim of the MS29-31AUTO leaky flyback goop of doom

i'm also going to ask Craig if the flyback can be replaced, i'll let you know if he can

[jonny]

sweetness, keep me posted. i think casey (califoreigner) is gonna end up keeping that blast and just fitting a new chasis. we'll see. i'll tell him about his place and maybe he'll just join for some tech help or something.

[jonny]

not many US members here but does anyone know of anyplace in the states that sells these chasis?

[Mr-Megalo]

i'll be hopefully getting mine from Australia

i've asked Craig about the flyback btw, doesn't look good i'm afraid

[Mr-Megalo]

Jonny, flyback is NLA

will post updates about the Wei Ya chassis availability when I know more myself,

[Mr-Megalo]

Jonny, i'm on the case, I know of a place that has 2 of these Wei Ya Blast City chassis in stock - and i'm hoping to grab one of them

[jonny]

Jonny, flyback is NLA


NLA? maybe it's just too early right now.

[jonny]

also, what's the specific chasis model # for the Wei-YA, casey wants to know cause he's going to call Alva, a US distributor.

[Mr-Megalo]

no idea till I get one as its not listed, its simply listed as being compatible for the Blast

[Mr-Megalo]

NLA? maybe it's just too early right now.
NLA = No Longer Available

[jonny]

no idea till I get one as its not listed, its simply listed as being compatible for the Blast

cool man.


NLA = No Longer Available

uncool man.

[Mr-Megalo]

chassis is on its way via EMS Jonny, once i've tested it works okay i'll post up an update

[jonny]

chassis is on its way via EMS Jonny, once i've tested it works okay i'll post up an update

sounds good. what did the final total end up being?

[Mr-Megalo]

around $270 USD IIRC

[jonny]

wow $270. i thought it was gonna be cheaper than that.

[Mr-Megalo]

it was approx $200 USD just for the chassis (approx £105 GBP)

[Mr-Megalo]

ooooh goodie, parcelfarce strike again
chassis is at there depot and has been since yesterday, however its awaiting customs charges, and as its Easter, they are closed today and Monday, and i'm in London tomorrow.

why do I get collared for customs charges on EVERYTHING !

[penrhos]

That'll be £15 VAT and £32 fees please and bend over so we can rodger you senceless while we play football with it for a week.

[cools]

Can deal with the VAT and fees, always factor it in when I buy something from abroad.

They lost my Christmas present from my girlfriend though.

Japan -> UK, fine. Came in, paid customs fees, out to be delivered, and it went missing between the van and the post office.

Submitted claim, took 5 weeks before they wrote back saying the responsibility lay with the original postal service. We had a perfect paper trail showing where it went missing :glare:

Fortunately Tokyoflash (the sender) had no problem with this, and sent another one out - arrived in 4 days without customs fees.

Best web company ever.

[Mr-Megalo]

£37.80, most of that being parcelfarce charges for paying the fee's on my behalf - twats !

and just to add insult to injury, I can't collect it till this afternoon IF it gets sorted today as there is a backlog, other than that its tomorrow

[Mr-Megalo]

right chassis is in.
will crack on with it tomorrow (too late in the day for me to start with it now i'm afraid)

[jonny]

quitter.


haha i'm excited to see how this turns out Mark.

btw, do you have a model number for the chasis now that it's in your posession?

[Mr-Megalo]

quitter.

its because i'm due to see the g/f tonight and having the house upside down and me doing other things while she's around wouldn't go down too well, I hardly spent any time with her at all over easter as I was a couple of hundred miles away from tinkering with monitors for JoeBlade

RE: chassis revision, I do, but i've been asked to not make this knowledge public just yet I will however pass you and kampong kid this info via PM - just don't go shouting it from the rooftops just yet :wink: it will be made public in due course as will confirmation that an alternative chassis works.

lets just say this, this chassis is in the same scenario as the Wei Ya C3129D, not many places have any stock, and they are a minimum order of 48 pcs from Wei Ya, unlike the C3129A which is readily available from many places

yea the reason for a part number was to see if a US distributor has or can get them.

this is great news though. as far as the g/f s concerned, drive it home for all us WPG'ers. lol.

*edit* i just found out who kampong kid is. it's funny cause i talk to casey almost everyday.

[kampong_kid]

hey mark- just wanted to say thanks. all your help is greatly appreciated.

[Mr-Megalo]

no probs :smile:

[Mr-Megalo]

right, the g/f decided to go and read for a bit
5 minutes later, lifted the tube up onto the side, connected up the chassis . . . . .

I think I am the reason for lack of public knowledge.

Megs, can you please post more pictures? I really want to get your opinions of this in low res.

Thanks

[Mr-Megalo]

I think I am the reason for lack of public knowledge.

hi thchardcore, I dont follow you mate, what do you mean ?

will post some pics of it in low res later today :smile:

[jonny]

this is such good news.

[thchardcore]

this is such good news.

Indeed it is.

I would love to see some cps2/3 on there but more than anything, for the love of god, a shot of a cross hatch. :wub:

Megs: Will you detail pot adjustments etc available on mainboard. I would like to really get your opinion of this screen versus the screen in an Egret 2. Mainly concerned on how it looks on Blast's Toshiba tube since people have complained of horribley contrasted scanlines etc.

Thanks

[Mr-Megalo]

well, from little chance I did get to look at it this morning 15k is pretty good, its no Nanao but its the best your going to get and the same quality as if you were to fit a tri sync chassis to an Egret tube, but obviously less curved
obviously fine tuning the RGB levels and focus pot on the flyback does help improve the overall picture quality.

pots on the chassis and remote are exact same as the C3129A as it is the same chassis just a different revision for for a different yoke, remote board has H size and position aswell as h-sync, V size and position aswell as v sync, contrast, brightness and pincushion, chassis has B+ for all 3 resolutions, V Lin, trapezoid and neckboard has RGB drive and RGB gain pots.
theres also a pot for rotation, but the chassis didn't come with a rotation coil to be fitted to the tube.

i'll get the monitor set back up again with CPS2 test grid in the next few days or so

[thchardcore]

Thanks Megs.

So Excited now. :)

[jonny]

anyways, if you want to do the chassis replacement
http://www.arcade-game-sales.com/products/sega-blast/5372-1.html



Hey Mark, that's the chasis you ordered right?

[Mr-Megalo]

thats the one, did casey ask Alva if they carried that particular revision chassis ?

[jonny]

thats the one, did casey ask Alva if they carried that particular revision chassis ?

i'm actually not sure.

[jonny]

ALVA only has C3120's, C3129A's and C3129D's.

[Mr-Megalo]

the place i got mine from had 1 left

[jonny]

yea mark, someone already bought it pretty much right when you told us about it i think.

they said they would get more mid-april, so here i sit...waiting...

i compared the burn in on my monitors (1 that's in a Blast, 1 that's on my floor) while they were powered off. they look really really similar and i can tolerate the burn-in on my vert Blast, so heres to hoping the one in need of a chasis looks decent too.

[Mr-Megalo]

right, so things didn't go exactly to plan with this tube and the cab it was s'posed to be installed into due to the once again differing mounting of the corner CRT mounting lugs between the highly curved Nanao's and the almost flat Nanao's and Sanwa's, was hoping to have this installed for the new owner to post up some pics of it, however, this tube would not fit into an Egret 2, so that means theres no chance of an MS29-30 or 29-31 fitting either, same probably goes for the Sanwa 29e31s aswell, which is a shame as i set the monitor up yesterday in 15k with 3rd Strike and 31k with Atomiswave FOTNS and I was quite happy with the picture quality and the intensity of the scanlines, geometry was really really good after it had been tweaked.
unfortunately though, this monitor / chassis was not destined to go in an Egret, so a quick run down to Cambridge and a monitor swap later with the geezer, (swapped him an almost Flat Toshiba Nanao MS29-31 tube and Wei Ya C3129B chassis for a more curvy MS9-29SU tube and a Wei Ya C3129A chassis and will get that installed into an Egret 2 soon (direct replacement)

so anyways, to summarise, does the Wei Ya Blast City chassis work, yes, does it work well ? say compared to the monitor setup in the AWSD, yes more so infact, I found far more adjustability of the sizing of the picture from being stupidly too small to being too big, and had no sizing issues at all, which I cant say i've found this so much on the C3129 used for the Sanwa tube, or the C3129D used in the AWSD. I have the say the Blast Wei Ya chassis is as good for the same reasons that the C3129A setup is good, its a Toshiba tube, it gives a decent picture in 15k aswell as 31k.

[thchardcore]

So, Mark, how do I get my Chassis now! :wink:

I ended up trading my Windy for a really nice Blast, but I need the chassis, or I need the original with leaky flyback fixed (no chance in hell jomac cann help?)

I am going to place an order, but no one it seems has one in actual stock at the moment, jonny hit me up I need to ask you some questions..

Blast is awesome anyway, just need to figure out the monitor.

Thanks

[Mr-Megalo]

theres no chance at all that Jomac would be able to spurce a replacement flyback so its either a replacement chassis or full replacement monitor

[penrhos]

What about cossmico?

their stock list shows

CHASSIS (666B1) 29'' 15 / 24 / 31Khz BLAST CITY /100-240V

10 in stock

190 USD

[Mr-Megalo]

now go and try and get them to confirm which Nanao tri sync that chassis replaces, is it for the MS29-30 or the MS29-31 ?

theres also 2 variants of the CH666B, theres the CH666B and the CH666B1

[AndyGeezer]

Ole Geezer can get brand new MS29-31A chassis, but they ain't cheap!!!

[Mr-Megalo]

what sort of price ?
IIRC you told me once they were about £500 or something

[jonny]

what sort of price ?
IIRC you told me once they were about £500 or something


ouch, i could just get a new toshiba tri-sync monitor w/ chasis for like $800 or $900.

thchardcore, what forum have you been frequenting the most? feel free to PM me at any site you've seen me on (either jonny419 or just jonny). PM SENT here though dood.

[Mr-Megalo]

ah, I take it ringo can still get those too then ?

[AndyGeezer]

what sort of price ?
IIRC you told me once they were about £500 or something

Yep, 5 brand new ones in stock in England.. ;)

I might get one for the toob, what do you reckon Meg? you reckon it is worth it?? OBviously I won't be paying £500, but yeah the retail price on them from Sega is £575 + VAT

[jonny]

ah, I take it ringo can still get those too then ?

yea that's an approximate quote from RingoC. he tried to find me a bunch of stuff i needed but never had too much luck. now i just get what i need from the SGO orders oxtsu places.

i really hope highway gets more of these in and isn't jerking us around.

[BOWER]

did ya get mi pms andy ?

(sorry off topic)

[Mr-Megalo]

@ jonny, they should do, just might take some time, they probably have the same minimum order quantitys as other places do

@ Andy, no brainer for me mate, i'd rather have a brand new Nanao chassis over a Wei Ya any day of the week, you know my thoughts on the MS29-31 - best monitor ever, plus you could do proper JPN spec machines, a Net City sitdown with Nanao MS29-31 and New Net with the Toshiba

[thchardcore]

Now I just need to possibly find some sodeart for one side. LOL:wub:

[thchardcore]

Can Megs or someone give me the flyback number. I might actually have found a site that might have it. I don't understand why you can't just use another flyback from a similar monitor?

[Mr-Megalo]

Craig/Ordyne asked me the same thing, there isn't one that is visible that I can see

[thchardcore]

I was thinking, there are probably only so many combinations electronically suitable for the flyback, couldn't we do a little research and find a suitable flyback to hack for parts. Hell, I'm willing to try a kortek flyback or any flyback from a trisync/semiflat combo with the same basic properties as far as deflection/impedence etc as an experiment. For the time being, I have a wei-ya coming, should be nice stuff, but I can only dream what the nanao looked like. Too bad my screen has some nasty burn on the bottom, but hopefully I'll just be too excited to notice.

:(

Anyone want a mint Nanao?? LOL, j/k..

Like Meg said, I could do original spec new net and net.. nice.. rubs fingers in a weird way..

[Mr-Megalo]

would have to be a sitdown to be different though, the standup JPN spec Net City is sooooo 2006/early 2007.

[AndyGeezer]

Well I got the legs and frame covers.. still, not sure I want to put stickers on those frame covers.. they is so pimping.. also I still in 50/50 if I should sack the ollie..

[jonny]

Highway is looking to get this new stock of chasis in, in approx. 3 weeks. i guess there were delays in production.

[Mr-Megalo]

from what I can gather wei ya do them to order, I think Craig had the same delays with the modified Sanwa variant's

[thchardcore]

I got my chassis today!

Megs, I will probably hit you up if the wei ya guide from killercabs ends ups not being the same.

I'll let you know how it goes.

PS: I want to install the rotation coil, any help with this (where to get it)?

[Mr-Megalo]

ooh theres a guide to doing this now then ? :laugh:

you probably wont need the rotation coil

[jonny]

WTF? They told me three weeks like one week ago. Maybe I got on a later order? Haha I haven't even heard back from highway.

[Mr-Megalo]

or maybe he ordered the only remaining chassis?
when i enquired there was only 2 in stock, I got one of them

[jonny]

well Mike's the one who originally talked with Highway and they said mid-April. I'm not really that concered about it but it seems kind of odd.

[thchardcore]

Megs, when I am plugging in the yoke wires, is the order

Green
Yellow
Blue
Red

and when I am using the black green/yellow adapter, the brown wire from the other pair of yoke wires (not the red/blue) goes to which color (green or Yellow)?

Also, there appears to be an extra hookup further away that is 3 pin, but a lot wider, what is this used for?


Thanks

[Mr-Megalo]

you should have a 2 pin adaptor that plugs into your yoke wiring, green and yellow I do believe, if you plug that in the wrong way it simply displays the image the wrong way around Upside down or back to front.
you cant plug the yoke wires into the wrong place as such as the 2 hori and 2 vert yoke lines are spaced out differently.

the 2 pin to 3 pin adaptor is for the power.

tell you what - take me a photo of everything you have and i'll circle it in photoshop and show you what goes where.

[jonny]

thhardcore, any updates?

highway keeps emailing me and telling me that production has been pushed back or there's a delay for this or that.

I fitted the Wei-ya, image is ok, not as nice as a nanao obviously. Geometry needs some VERY REAL tweaking. Looks like I will have to tilt the yoke a bit to get the image even, unless MEGS knows where to find the rotation coil.

Thanks

[Mr-Megalo]

tap up someone who bought a C3129A or a C3129G - IIRC both those have been known to come with a rotation coil, the C3129B didn't

[AndyGeezer]

I've chucked out about 4 or 5 rotation coils.. might have one kicking around, but did a massive sort out and chucked a lot of bin fodder.

Space is precious.

Please let me know if you do, it would help a lot.

I'll post pictures of the cab, as I just got a new white control panel surround !

SCORE!

[thchardcore]

The picture is fantastic, but there is an issue. The picture is compressed on the right side and then expanded on the left side. Such as the picture below:

Now, keep in mind the original chassis died, and I had to adjust the yoke a bit to get a good picture, which is almost perfect geometric. What is causing this? Is it Yoke related or is it chassis related. I can't find a wide/thin plug or a horizontal linearity adjustment. The chassis is a Weiya M3129B. Yoke is ruled out actually, take a look at the photos.

[Mr-Megalo]

I can only give some limited advice on this i'm afraid.

that is a linearity issue, to which there is little you can do to solve as IIRC there is no h.lin pot on the M31 series chassis's.
normally when you adjust the V.Lin pot you get this same issue with the bottom of the screen, yours looks like a horizontal lin issue, and as theres no pot, theres not alot you can do that I know of, although recently someone I know who fitted a Pentranic M2929 to a Big Century had the exact same issues Harry @ Pentranic told him that he could try using small magnets at the back of the tube to straighten the image out, but I haven't heard from him since to know whether he solved it or not.
a rotation coil *may* help pull the image into line a bit more, but you've done a spot on job with adjusting the yoke as it is.

might be worth dropping a message into Craig Walker / Ordyne www.giz10p.co.uk and see if he can suggest anything, but he is away till late next week.

glad you are at least one step closer to having it all sorted though, besides the image linearity issues, how are you finding the cab and the quality of the picture in general in 15k ?

[Mr-Megalo]

anotjher question, if you move the image along with the hori position pot, does the same section stay the same size ? say if you move the entire image to the left

[thchardcore]

Yes, those 3 lower photos are with the picture moved in, sized to minimum, indictating the linearity problem is from the chassis not the yoke. :(

15k looks amazing with 3s, almost as nice as a nanao, almost.

FUCK this shit, I feel shafted, I want another chassis, this is bullshit. :(

[AndyGeezer]

Found some rotation coils..

If you want MS29-31A chassis, I can get them £500 odd though.. :(

[jonny]

mark, andy, anybody....

is there any preventitive maintanence for evading the flyback gooping out? i'm gonna be pissed if my working two crap out.

[Mr-Megalo]

from extensive discussions with Craig over the past cab orders we've been through besides dry joints due to age that was one of the major issues with the MS29-30's and Tri Sync Sanwa and even the Wei Ya C3129a's theres not alot you can do really, even I have to say the issue with the flyback on the MS29-31a is a pisser but its something even I knew nothing about as mine was NOS ( I still stand by the statement that its the best monitor I had!)
its something that plages not only the Blast monitors but nanao's and monitors in general and the fact that somthing like dry joints can end up takng half the boards components out, components that are either previously custom made or NLA makes me a sad garden gnome.

this is why some people keep old chassis's, so they can rob parts off of them if needs be.

last i spoke to Craig, he had also asked Joey if the flyback was an obtainable part, I think the reply went something along the lines of spares for Nanao's haven't been available since back in the MS8 days

[jonny]

i understand that but when the flyback leaks, it is just a matter of corroding out the silicon seal on the bottom of the flyback? could you maybe add an extra layer of silicon? a second level of defense if you will?

[Mr-Megalo]

I couldn't say, that would be something to ask someone like bob roberts, craig or joey or similar

jonny have you ever experienced the singing flyback issues on any cab ?

[jonny]

i'm gonna say no.

[thchardcore]

Fuck the Wei-ya.

I stuck a back mounted ms9-29su in there without bezel issues :) Fits like a glove.

[Mr-Megalo]

so you rear mounted the MS9 tube to the frame and it fitted in place okay with NO other modifications at all ? not even any washers to space the tube out from the frame ?

[Mr-Megalo]

bit of an old thread bump

Craig has Nanao MS29-31A chassis's due in soon, should also know soon whether they will work on the MS29-30 tube/yoke
