I have a very nice DK3 stack I would like to get finished up.

Both RP2A03 test good
Poking around the board with @philmurr audio probe I get different game sounds but nothing feeding the amp so out of the speaker I get zip.

I am using a jamma adapter with an amp built in. Yes that amp works.

I have tried finding schematics so I can track it further but the best version I can find is illegible.

Any help on where to poke if you know, or if there is a clean version of schematics, please send them over.

Am excited to button this one up. My one buddy is a huge fan and he's offered to play test it for me once the sounds work.

Thanks in advance.
