Sanwa 29E31S - clear schematic needed

[jrr]

I have the pdf one can find online for the Sanwa monitor, but the schematic is perhaps 100 DPI and quite useless.

This was used in Outrun II and Mario Cart GP II. Someone MUST have an original manual and is able to do a better scan than the current Ver1.2 manual shows - here is the copy I found:

Someone should be able to improve on that!

Thanks!

i just bought the paper schematics on line
i can send you pics

Thank you, any chance you could scan them at 300 or higher DPI? Photos are probably better than what I currently have, but scanned images are much easier to clean up and are usually more legible.

I appreciate the offer none the less, if photos are what you can do I can work with that.

Thanks!

i don’t have a scanner

fair enough! Where did you find the document for sale? Does the seller have more?

In any case, nice flat photo(s) should help a lot.

Thanks!

This one help any better? It's version 0 though.

or here, version 1.2 revision B, might be the same as yours though:

There was one for sale on here, could check if it's still around:

Resurrecting an old thread, did anyone manage to obtain an actual service manual or a higher res scan? I'm trying to work something out on the schematic which is impossible with the links above. Thanks.

 

[Retroman839]

I have one
Not sure if it’s any clearer though

Mario Kart used a pureflat version didn't it? If so, that would be the 29PF31. Chassis is pretty much identical to the 29E31S to look at, although there may be a few components with different values to work with the flat crt and yoke.

Hi, I’m also looking for a clearer schematic for the Sanwa 29e31s if possible please?
Also, can anyone with a Sanwa 29e31s confirm if the step-down transformer they are using with this monitor is an isolation type please?
A photo of the transformer either way would be really helpful as well if available please.
Thanks.

Simple answer yes

29e can run on 240v

240 to 110 v transforme found in sega Naomi cab is

It all depends how you want to wire ( electrify ) your cab ?

These sega transformers come with multiple voltage outputs .

Some come with 3 or 4 different voltage outputs that where particular to the game it was supplied with.

For example sega Naomi sound Amp is 17v some supply this voltage
As well as 5v & 12v. , 24v
& 110v ..

So you need to decide what you want overall for your cab

es31 runs on 90-130vac only
it won't need an iso type
according to my manual the power rating is 160w +/- 20% which would mean 200w is more than capable

 

[Retroman839]

Im sure I have a 29e that says 110/240v in ?

 

[gunblade]

the pfx can run on 110 or 240

 

[Retroman839]

the pfx can run on 110 or 240

😊 glad I didn’t try it..
I’m going to look later ..
Last time I powerd up the 29e
I thought I sa 240 v in

blooody glad I don’t try it now 👍
