What is this your "Cinematronics/Vectorbeam rare games that I own list?" ;^)

The original speakers were rather inefficient, and the old way
Cinematronics/Vectorbeam used to adjust volume only gave it a limited range. By
changing the pot you could make the volume louder, but the volume is at minimum
with the pot shorted, so changing the pot won't make it quieter. Check out the
way they connected the pot in Star Castle. Do the same and your volume problems
will go away.

I haven't replaced the speaker yet on my Warrior but the volume control is very
touchy! It does need a molex connector for the control panel. Some previous
operator needed one and just cut this one off!

Check all the ROM connection cables on the Boxing Bug very carefully, I had some
problems with that on one of my boardsets. The other working boardset is in the
Boxing Bug cabinet with a monitor in desperate need of a LDV2000.

As far as Speed Freak, the giant blotch is most likely the trace being projected
way off to the side, which is why the circuit breakers blow. The most common
reason for this is the ribbon cable is connected upside down. If that's not the
cause, then the LF13331ND would be my second guess followed by the DAYs. Does
another CPU drive the monitor ok? If so, look at the driver ITs on the Speed
Freak CPU.

My Speed Freak needs a new steering wheel PCB which was simply missing when I
got it. Just need time to wire wrap one up.

So have I helped and one up'd you at the same time? Heed hee. The final card
has yet to be played...

sure looks nice!"
