I'm looking at having my Atomiswave SD monitor and Chassis recapped and wanted to know what recap kit I need to buy and from where?

Here's the details:

Monitor: WEI-YA M3192D
Chassis: WEI-YA C3912DB

Thanks!

Someone else is going to do the recapping for me

The CRT tube isn't a wei-ya, its probably a samsung, LG, or philips.

The chassis is a wei-ya M3912D probably

The only difference between M and C is erm, monitor (whole unit with chassis) and just chassis alone, hence the M and C coding.

Why are you getting it recapped? Its only about 6/7 years old, are you experiencing growing/blooming issues?

Its just a cheap trisync I'm afraid, your best bet is replacing it with a sanwa PFX or toshiba trisync. Recapping it, well it'd be the cheapest option, are you going to replace the caps with higher quality ones? I doubt they are nearing the end of their lives.

kernow, 6-7 years is plenty of time for caps to fail. I've seen caps last 6 months. And doesn't need to be said, that Wei-Ya probably use the cheapest shit they can get their hands on.

360heelflip: Are the caps visibly damaged at all? What symptoms are you experiencing?

I'm also in Melbourne, and if necessary, would be more than happy to do the job for you if you supply the kit. Bob Roberts is a good source for them and his shipping rates and service are second to none.

I guess, and you're right they do use cheap components. Thing is I'm pretty sure the symptoms he's experiencing are probably the same as any other AWSD monitor.

It'd be interesting to know if replacing the caps with better ones tightens it up somehow though, hmm.

I need to find someone who'll do MS9 cap replacements.

Unlikely, perhaps using low-ESR caps could make a slight improvement.

I've got a guy in the UK that can do it for you, however he's in York :(

Is that Ordyne/Craig?

Apparently he doesn't touch MS9's for the sheer amount of caps in them.



Anyway so if this guy is planning on replacing the caps in his wei-ya chassis just to improve/lessen blooming and geometry problems, its probably not going to work right. Thats just how the AWSD monitors are, far, far better in high res, medium to 'ok' for low res like neogeo and cps2 etc.

No, its actually a friend from IRC who I'm sure would be willing to take on the job for the right price.

Must admit I've never used one. But obviously, 31khz is what they had in mind when designing the things. Wonder if its worth changing the chassis?

I can source chassis which can be made to work on just about any tube from Perth. However, they are unfortunately only dual res (15/24).

Suffers from "Wavy Display" Making the Vertical lines on the sides of the screen wavy as all hell, make any sense? Left bottom of the screen also sort of bends up. When you're looking at the test screen of the MVS the left and right vertical sides are totally wavy and not straight at all.

It does sound like a potential cap problem, since a kit is only a few dollars that'd be my first port of call.

Dont suppose you know anyone with an ESR meter?

Thats what they do in low res, you can correct it a little by removing or tweaking some of the magnetic strips attached to the back / neck of the tube.


I challenge you to find a single person with an AWSD who doesn't have low res geometry problems. Honestly, its what they do.

I think we really need a picture so we have a better idea of what we're talking about here. I get the impression this is a bit more serious than the substandard picture cheap tri-res chassis' give in 15k.

I just sold my 1 slot MB to get a 4 slot, which I won't have until Monday. Once I have it, I'll post some photos.

Not a problem, keep us posted.

For interests sake where are you located? Im in the Dandenong area.

Keep in mind you'll need to rewire the speakers in your cab due to the multislots outputting stereo via the JAMMA connector.

JAMMA:
Pin 10: Speaker +
Pin L: Speaker -

MVS:
Pin 10: Left Speaker
Pin L: Right Speaker
They share a common ground.

Its not difficult to hook up a switch to switch between the two, or jammaboards.com sells a JAMMA to MVS adapter board which has been quite highly recommended by a few members of the site.

Failure to do so will result in you blowing the power amp on your board.

Also, there's a Mono/Stereo switch in the Atomiwave SD cab

Oh, really? Its likely ready to go then. Check what wires go to where with a multimeter to be sure.

And yes, thats the board I was talking about, however it doesn't sound like you have a need for that anymore.

I had MKL make me a harness up which was a jamma extension with cutoffs for L+R audio, it allowed me to plug a four slot straight into the cab with no adaptors and the only downside was relying on a universe bios to get into the test menu (or flip dip 1), as test would have been relocated and not usable. On the unibios I'd just bring up the in game menu with start+ABC, then select reset, and hold BCD for the test menu so it wasn't a big deal at all.

With a 7 button starcab panel and overlay from Maxchainsplendid, it made for the perfect MVS/CPS2 setup pretty much. :)

Got the 4 slot today and the Naomi wires in my Atomiswave SD cab already ahd the 4 PIN stereo connector and I'm getting full stereo :D Just need to get the wire from MKL for the select button and I'm all sweet!

I think you might need to disable jamma audio too due to a wiring issue with the AW cabs where it has mono still enabled or something even when switched to stereo, don't want to damage the sound amp in your 4 slot thats all.
