I have a Midway Gunfight PCB that I have fixed, except for some weak audio. The sounds should be strong and full with somewhat of a lingering echo. The sounds are there, but lack the full sound as described.

I have already turned up the volume on the potentiometers, which helped at first, but that has not corrected the rest of the problem. Any ideas what might be wrong?
