Today I looked at a System 1 cab that had been converted to Smash TV. I was originally told they thought the speakers were blown because the sound is all distorted and vibrating, kind of like it is passing through wax paper.
Well, I get there and find that the speakers seem to be just fine.
So, what is causing the problem? I figure it is one of three things:
a) Incompatible speakers - these are 4" 4 ohm speakers. Is it possible that the JAMMA Smash TV needs 8 ohm speakers or something? Do they make a 4" 8 ohm speaker?
b) Problem with the sound board - either a voltage issue, amp problem, etc.
c) Problem with the wiring or volume pot - it has an external volume pot like older Williams games. The volume goes up and down smoothly, with the same distortion at low levels as at high levels.
What do y'all think?
