I believe the mystery is at least partially solved. The tube situation was far worse than I thought. Of the 41 total tubes sent to me by my Audiogon seller, 29 tested bad (no conduction in one or both sides of the tube) with the tube tester. I don't have enough good tubes left for even one amp.
Since the tubes were sent separately, I have no idea how many bad tubes I put randomly in each amp. I thought (by visual inspection) that I had 5 good tubes in the amp I did most of my testing on. Turns out some of these were bad also. No wonder I was having trouble.
I'll get some new tubes and try again.
