6922 tube selection

Try some Tesla 6922s. Nicely balanced sound, never objectionable. I use them in my CJ Classic Sixty amp. Previously had the CJ stock supplied EH, then switched to the Genalex 6922 re-issues, liked them at first, but later found them a little hyper sounding. Of course, YMMV. Good luck either way.

I'm not as savvy as others here about tubes, but also have tube pre and amp and also had trouble swallowing a whole system upgrade cost-wise. The option that worked well for me was to identify which tubes had the highest impact on sound on my equipment, upgraded those first, then the next, and so on.

Search here in the forum who are the good, knowledgeable vendors. Talk to them.
Search the member system pages seeking the same equipment you have and ask them what has worked for them.

As Truman said, don't go cheap. It doesn't mean buying the most expensive tubes, though.

Call Andy ASAP for the only honest tube guy.

Might also try calling Brent Jesse, knows his tubes, not pushy, and reasonable prices on NOS tubes. No affiliation, just a satisfied customer

"Call Andy ASAP for the only honest tube guy."

Really? There's only one honest tube guy on the whole planet?
