Howdy-
I picked up a Medusa.
There is a sound issue that I can't resolve by adjusting all 3 pots (coin door master volume pot, sound effects volume pot on S&T, & voice volume on S&T).
At first, I thought that there were no sound effects at all, just voice. It turns out that the sounds are there but reeeeeeeeeeeeeeeeeeeeeeally quiet.
I've currently turned the coin door pot up to its max, turned the effects pot up to its max, & turned the voice pot down to almost nothing. This makes the effects & voice roughly the same volume as each other, but there's a good amount of hiss/whine/pop b/c the gain is up so very high.
I've semi-cleaned the 2 S&T pots (alcohol & toothbrush w/out removing pots from PCB), which removed some "crunching" when turning the pots, & I've cleaned the header pins on the S&T, & I've reseated the 2 connectors on the S&T.
What might be the problem? The speaker sounds good, the sounds sound good, the wiring seems to be good, it's just that the effects volume is pathetically low. New pot? Bad cap or resistor or something in the sound effects part of the board?
Thanks,
-Jason
