6922 Tube Question

I need to replace a pair of tubes in my VAC Signature.  They are 6DJ8 6922's.  Though I've had tubed pre-amps for years, this is my first tube replacement.  So I have a real newbie question.  Are all 6922's interchangeable?  Can I use any 6922 or must they be 6DJ8 6922's?

ps - ya, I know, bad time to need tubes given the world situation.

6FQ7 for me.

Not the same tube at all. Different gain, voltage ratings, and bottle length.

It is a 6SN7 in a 9 pin bottle.

I dont think he was saying that they were compatible.

Who said anything about "same?" And what's that got to do with sound?

6np1 (6np1-ev) might worth a try even though it is not an exact match to 6922 or 6DJ8. My phono preamp comes with 6np1 Russian tubes, but the designer of the preamp also suggests to use 6922 or 6DJ8 tubes. Actually, I prefer 6np1-ev tubes over bugle boy 6DJ8 on my phono preamp. They may be the cheapest 6922-ish tubes you can find.
