Re: Asteroids Deluxe sound problems

Okay, problem solved... the guilty party was Q7 on the Audio/Regulator
board. If anyone in the future seems to have almost no high pitched sounds
yet all of the low pitched sounds, check out Q7 (TDA2002A closest to edge of
the board.)

Thanks so much to everybody,
