This board (Namco y112960101, used in Ace Driver and some redemption games) works great, except for it appears the audio amp is dead (speakers and volume control getting voltage and all wires are fine, there's just no specific audio signal coming out of the PCB). There are no schematics for the actual board available, though, and I'm a PCB repair novice so I'm not sure which chip the audio amp would be... I mainly work with older games that have separate audio boards, haha. I do know the chip pointed out here involves sound, would this be it or would it be one of the pieces attached to the heatsinks at the top? Is it easy to tell from a glance which piece it would be for testing/replacement purposes? I can get individual chip numbers and IC positions if that helps (along with better pics) but I know audio amps are usually visibly different from the CPU and other chips so I thought maybe it would be simpler than that, I'm just too dumb to know what I'm looking for
Thanks
