Ok, some more stuff. Ive been running this with Tekken tag and Tekken 3. I tried a Tekken 2 board and it Works fine. So there might be a timing issue on system 12 vs 11 boards. I’m out of amplified stereo pcbs to try, but this is the only theory that seems to fit.
Did a bit more investigation. Pulled out the setup and put it on the test bench. The cab in question is a Namco Soul Edge cab, which has pots inline to the speakers, so i wanted to sanity check it. So out of the cab I wired a spare speaker to the right channel directly off of the kick and both...
This is what I’ve come up with. I’m having an odd issue where there’s no sound on startup. If I pull the right speaker output and turn it on I have left channel only. If I reconnect the right channel while powered it works in stereo. If I turn it off and on again it’s back to no audio. Any ideas?
I'm considering using a riddled TV switcher to put Tekken 2, 3 & tag into my Namco cabinet. The cab uses the onboard amplified audio, using the left channel from Jamma pin 10 and the right channel from the kick harness pin 1.
The switcher works by using Jamma pin 10 for audio left and 11 for...

So yes, they were once connected to ground. Most of the time they just cut the traces. You can sand off some of the solder mask and bridge to ground again, or use a bodge wire and just connect it to ground wherever.
Since this is basically a genesis with a jamma edge, I wonder if it's possible to swap roms to change games? Maybe even figure out a way to get a everdrive on it? Lol, at that point, probably easier to get a JAMMAtizer genesis.
Jury’s out on the chinesium audio mod. There’s a lot of components that are missing or subbed. You’d have to replace a lot. That being said the of the two boards I’ve had in my possession 1 came with issues, the other seems to be fine.
