I have gotten away from the 6922. New production is not that great. Old stock is drying up fast ....
I had a CJ Classic 2 preamp, it was tough on tubes. Only a few would last long, the Gold Lion 6922 or a Reflector 6h23n eb were the only 2 that would last.
Unless you have a tube tester you'll never really know what you are putting in your gear. I took a bunch of 6922 / 6dj8 and most were not as advertised, weak or mismatched triodes. This was more so with new production but had a few "NOS" duds.
I have one component that still uses them , I have EH 6922 in there now . They will at some point be replaced by Gold Lion 6922 as I think those are the best new production. JJ are good too , but when ordering either , one should request matched triodes and matched tubes if ordering pairs.
