6DJ8 vs. 6922?

Alright tube aficionados, are 6DJ8 and 6922 tubes inter-changeable? I would ask Roger Modjeski or Tim de Paravicini, but they're both dead.

Anyone care to name their favorites of each tube, for use in phono and/or line stage pre-amps?

The tubes get noisy more quickly. You might want to research Russian 6N23P (their version of the 6922) or 7DJ8s. Both are supposed to be a little sturdier than the 6DJ8 family.

I have not liked any of the modern variants very much.

Supposedly used by c-j in some of their preamp that burn through 6922 tubes. The Tube Depot appears to have some in stock. I have two quads and nothing to use them in. Lol. I didn’t get to try other tubes. I ended up returning the 17LS2 because it had a noise issue (not tubes).
