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.
