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?

     Whatever, "misinformation" MIGHT be found: the OP asked if the mentioned tubes tubes are interchangeable (6DJ8/6922) and favorites.

     No iteration mentioned in this thread* IS NOT directly interchangeable, with those, in a circuit designed for a 6DJ8 or 6922.

                             +1 for Brent Jesse's observations.

                       A wealth of listening impressions/info, here:

                       *Outside of the 12 Volt tubes mentioned, obviously.

 

I’ve tried more tubes in this variant than I would care to mention. Oddly, favorites were the Amperex 6DJ8 with a white globe. I’ve never seen these anywhere else, and they sounded better than other Amperex 7308 (military spec) with white lettering that are $$$, despite the 6DJ8 spec supposedly being the lowest of 6DJ8/6922/7308. If you can find any Amperex 6DJ8 with a white globe on em, try it out. 

The Amperex JAN 7308 is white good as well, as is the Reflektor 6N23-P. The latter are still available on Viva Tubes, where I’ve purchased some in the past:

I went to NOS Amperex 6922’s and they are wonderful.  I tried several different ones and the Amperex were the best to my ears. 
 

All the best.

agree w @rodman99999

no misinformation posted here that i see on the op’s basic query

i have probably ~1000 pcs of 6dj8 variants i have collected over the years, from european cca’s, ecc288/188, 7dj8/pcc88, bugle boys, a-frames, tele’s, adzams, mazdas, cifte’s, russian rocket 6h23p’s and so on... reason being i have been a c-j preamp user since the 90’s, and for many years, my beloved premier 16ls2 used 6 at a time

folks who have answered here to the op like myself and rodman999 have a substantial experience base with this tube (and tubes in general)

that said, i don’t know why one commenter went on about 12au7 5814 etc etc... got nothing to do with a 6dj8 except the physical tube form
