 Now that I have had a chance to photo, and disassemble the unit, here is what you are looking at. Basically a Quickie and PJCCS that need attention. I must add that the 3 position Glassware A3 volume control is a stepped attenuator arrangement for 1) master volume (center dial), 2) left and right separate volume (flanking dials). This isn't the issue..... Believe it or not, I am unable to get the PJCCS working when wired to the Q. The Q works on it's own. Each time I make one of these simple kits, this same thing happens when the PJCCS is wired in, i.e. no signal at output. I realize that this is something that I am getting wrong, but I have simply lost patience.

That's probably a little beyond my skill set.

I took this pair of old Paramours in for repair recently.  One of them somehow developed a short between B+ and the chassis through debris in the 9 pin socket.

Since I had the amps in hand, I talked the owner into letting me install the Iron Upgrade package that we offer for older SEX amps.  It fit, but just barely!  I had to trim off some of the mounting tab on each output transformer so it would clear the wood base.
