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 first thing to read in learning about the 6DJ8 family is brent jessee's 6DJ8 page. 

someone else posted it. 

also, lots of people here are quick to offer misinformation. its often swift and immediate. its worse on facebook groups.

learning the 6DJ8 family begins with familiarizing yourself with this information here. its not entirely correct, but its the best out there. 

     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
