I am working on a fish tales where two of the tantalum capacitors were blown up. I replaced them and a repaired a trace that they had damaged. After that didn't work I replaced the main amp (with the big heatsink) and all the caps other than the big 2 which were testing "OK" on my ESR meter. When I turn the game on it makes a big buzz for a second, then silence. Any other ideas before I scrap it? A few other questions:

Is it okay to play the game without the sound board installed

Is there a way to "bench test" the board without putting it in a game and turning it on? Any recommendations on where to send the board for repair if I give up?

Is the Pinsound board the only direct replacement available? Almost $400, yeesh.

Haha I should have been more clear!
