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.

6dj8=ecc88=cv5358

6922=e88cc=cv2492=6n23p(Russian)=

6n11(Chinese)=cca=cv2493

7308=e188cc=6n23p-ev=cv4108

All in 6922 & 7308 family are interchangeable and if your circuit permits then and any of the 6dj8 ones.

6np1 (6np1-ev) is a different tube and most likely a modification in circuit is needed.
