6922 vs. 6DJ8 vs,7308


Are these tubes interchangeable? I have all tubed systems, and the time has come for me to replace them with newer ones. Can I switch one from the other? What is their difference in terms of voltage use, quality, etc...
thanks to all of you who are techno scholars, you have been super helpful!!

I would caution against the over reliance on any "pecking-order" with respect to "good-better-best" with these tubes. Aside from synergy with particular components, there is variability between brands and even between types within brands. For instance, I had a set of military-grade Telefunken 6dj8's that were much sweeter and less microphonic than MANY of the 7308's, 6922's, and Cca's that I also tried. Also, don't let anyone fool you into thinking that all gold-pins are better than all steel pins.
100% aggree with 4yanx as to a pecking order of quality as it pertains to sound quality - it depends.

I know this is a very old thread, but Clueless, do you have that list?
