Kyle - We did have fun and it was nice to hear from you, at least until we 
"lost" you in that tunnel!

The tracking on the 1 mil Cobra was off my gauge, the manual recommended 10 
to 14.  Ouch.  So I did reduce it to 10 grams.  I know that still seems 
heavy, but if I set it lower, it might have trouble rejecting and skipping.

It does sound pretty good, but I don't think the Cobra is as forgiving on 
worn records as say a lightweight magnetic pickup.

The latch solenoid problem turned out to be a matter of adjusting the leaf 
switch that shorts out the 68 ohm resistor - it was making contact in its 
normally-closed position, and was not shorting the resistor.  Thus the 
resistor was always in series with the latch coil and there wasn't enough 
oomph to pull it in.  I also saw some contacts on the letter switch that 
weren't being actuated - the box still selected, so I guess maybe it was 
part of an anti-cheat circuit?  I adjusted those.

I wanted to study the wiring diagram, but at this point the ladies took away 
my screwdriver and were trying to get me drunk.

Cheers!
