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?

Telefunken, Amperex, Mullard et al are all good NOS tubes. But I just put a pair of EAT 6922 tubes in my GAT and I must say everything improved by quite a margin.
