Just my luck, I bought a NOS Asura Busters only to have no sound come out. I am running this through my HAS, and using the un-attenuated audio jumper I can actually hear pretty much everything. It's suuuper faint, but I can at least hear sfx and music. I can also turn the sound pot and get the volume to raise/lower so I assume it's fine. My first thought was the LM324 preamp was busted, so I replaced that. Then I swapped out the actual amp with another one, also no change.
So I'm left wondering, is it the Pre-amp or the Amp, but my replacements are also bad? Is it the pot?
I changed out all the electrolytic caps, but not the others. My Z80 seems to be getting plenty of voltage (5.0. The LM324 is getting a bit less (4.6v).
Looking for some thoughts on what to try next! Thanks! Here's the sound section...
