Buy tubes from Audio Research or not

Yes I think so, I'll send an e-mail.

Check out TUBEDEPOT SED SV6550C. Just order matched quads or better yet 8 matched tubes!!

Taters if you're worried talk to Howard at Audio Specialists in Studio City he's a great tech, repairs ARC and will know what does and doesn't causes problems.

Taters check this description with pictures!!
This is from The Tube Store SED Winged "C" Tubes page.

Yes! If "your guy" only buys 8 tubes how can he get two matched quads, he doesn't have a big enough inventory to choose from. Is he supplying SED Winged C 6550's ?
Taters what about the (4) 6922 input and the (4) 6922 driver tubes? Are they still good? This appears to be the more difficult area of VT 100 Mkll tube replacement.

Boneman thanks for the clarification Mklll.

Taters
You might ask how much to bias your tubes, two matched quads from Tube Store or Tube Depot. Tube Depot marks each tube in the quad with it's value.
