I, too, agree that your expletive is very appropriate for this line of business, especially if you are struggling with a PQ2! I've been there brotha, and I know it can push some buttons trying to get that beast to behave. Toward the end of the our PQ's useful life we had a visit by 4 VG reps, two service guys and two sales guys. The VG guys were ABSOLUTELY certain that the torch box wasn't grounded properly due to negligent maintenance. They were very accomodating and tore the matchbox off and cleaned up all the sites of contact and reassembled. It didn't make any difference in the instrument performance. I can recall letting a few damn's and other more colorful expletives loose from my lips during those trying times. Hang in there!
We did finally discover a defective quad RF controller/generator set was the cause for the poor instrument performance. We got the PQ running again with the new SX-300 quad controller and RF generator combo, which, by the way, are available as spare parts. I certainly don't claim to have the answer to your PQ's problems, but wanted to check in anyway.

I am still unable to get the machine running properly. Apparently there
were similar problems which were resolved by fixing the grounding in the
torch box. Can anyone think of a reason for signal instability and poor
sensitivity which may be due to a front-end electronic problem (torch box,
RF generator, etc.)?
