I've got a friend down here who recently purchased a used VT 100 mkII, some Alon Circe's and a Audio Aero Capitole mkI CDP. A couple of months ago, when we first met, he asked me to help him set up his system, being more into HT. I went down and we set everything up, but prior turning everything on for the first time, I tested the output and input tubes on my Triplett 3423.
When we finally got things squared away and turned the amp on for the first time, we got a transient that seemed to pop a 110 ohm resistor for some reason. Although the amp fired up, the right channel was only running on three tubes. We ordered the part right then and there. Due to his family coming, it was a month before he brought it back and I soldered it on. I went down that week and did a power tube bias and things worked well. I used Abe's site for pointers, but I really never tried to fiddle with the input drivers and their bias. If it were my own amp, I'd muck with it, but I don't want to screw around with a delicate procedure on somebody else's piece of kit.
What got me was the complete kit comprised of 8 6550Cs and 8 6922 Sovteks selling through AR for like $1650. Anyway, things seem to be running well for him and he's happy. It's just a lot of cash to retube those suckers using NOS tubes.
Good luck, Chris
