RE: Driver tubes for Counterpoint SA 100

Posted by Sondek on March 8, 2017 at 13:47:24:

Back in late 1980's I bought a new SA12 and later had it upgraded to an SA100, and then again to the NP100 status by Alta Vista. Unless you want to chase increasingly sketchy and expensive NOS, I'd highly recommend the JJ 6922's. Make sure to pay for selected and tested ones. Been a while since I've bought any, but you should probably expect to pay ~$30 each for them plus shipping. The JJ's have a neutral tonal presentation that is very reminiscent of the Tele 6922, IMO.

If you want to chase NOS, DAK's recco of the Amperex is a good one. You may also want to add Siemens 7308 to your list for more sparkle and punch. Amperex 7308's are nice too, but I had a predilection to the Siemens in my old Counterpoint.
