Good morning -
I have a Golden Tee '99 (that is a conversion from what looks like a Mortal Kombat game).  Anyway, the volume is very high, and the knob (I will attempt to attach pictures) doesn't seem to be working.  I am curious if this is a secondary volume control, and could there be another knob somewhere else?  If not, does anyone know if I can fix/replace this one?  Any help is greatly appreciated.
