I'm surprised no one has mentioned the Genelex Gold Lion 6922 re-issue. I like it very much in my CJ Classic 60 amp. You might want to try it in your CJ pre-amp.
Good 6922 tube for my CJ ET-3 SE pre-amp?
This is a follow-up to my recent thread on lowering the noise floor produced by my CJ ET-3 SE pre-amp. I called CJ and they seem pretty sure the issue is in the stock tube (Electroharmonix 6922) and even suggested I try a Telefunken. What other 6922's (or equivalent) should I be considering?
