Anyone have a Tetris bootleg they can rattle off cap values for me?

This one boots and plays but no audio. So since most of that caps in audio section are missing or half off the bosrd im assuming that's not helping.

Any help is appreciated.

Layout isn't similar to OG Atari pcb so hoping someone has one they can look at.

All pics on web are from top. Can't find any side shot with cap values.
 
Check the Vcc pin, looks like it has a cap missing on that rail, perhaps missing power to the amp. You could apply Vcc and check input/output using an audio probe. Also, pin 1 (input) looks to be a hack repair.

EDIT I read the pinout wrong, the hack is on the Vcc pin. Still though, an audio probe is useful here.

Pin 8 is repair. It's shit.
Waiting on @Charles Kline to send over some pics and I'll get it all capped up and report back.
 
Looks like 220uf 25v. I've also came across some boards that had missing caps, but it still seem to work just fine.

I was wondering about the missing caps and still working myself.
Not an expert but I think some caps are for smoothing the power, so if the power the board gets is ok quality it usually doesn't need it. I had an outrun PCB that had those power filter capacitors shorn off and was working fine and that's what I was told.
