My audio amp isn't toast....But
Ummon:
There's an audio amp in my Capcom Impress. It looks fine, though as we know that doesn't necessarily mean anything when it comes to electronic components. With the Tetris board that came with it, there was no audio. I'm assuming it was mono, as the rca connectors weren't being used. I connected my computer audio out to those and no audio, either. I did have the main switch inside the cab on. What else can I do to troubleshoot this?
SirPeale:
First, check to make sure it's actually getting power. Check the fuse as well *with*a*meter*.
Assuming those requirements have been met, I'd bet on the amp transistors being toast.
Ummon:
I'm not used to checking fuses with a meter, but I got no readings when I touched the leads to either side. I made sure the cab was on. (Incidentally, I noticed the monitor has to be plugged in to the PS for anything else to turn on. Is this what's meant by a switching PS?) I also tested what I thought were the hot and ground(s) that connect at the back of the board, behind that big heat sink, and nothing there either.
DJ Infinity:
I have a coupla NAOMI sound amps. They look similar. If Ya want one you mave have it. I have no need for it. My cab(s) use powered speakers. :cheers:

Ai...that's not how you check a fuse. Pull the fuse, set your meter to ohms. Probes on both sides of the fuse, but make sure you only handle one side with your hands, otherwise you will be reading your body, not the fuse.
