Title: Tube rolling comparability questions
Post by Sonic_Alchemist on 06/01/20 at 15:01:55

I have a bunch of rectifiers laying around and was curious if I’m able to use gz37 or 5r4 would be ok to use in the TJ. And should I rebias the amp any time I swap rectifiers?

Also, if I roll my power tubes to 6l6, 807, kt77, or kt66... do I still set the bias to .825?

Any help would be greatly appreciated! :)

Any tube change on Tori Jr, requires bias check adjustment.

Yes, but my question is if I change to a kt77, 807, 6l6, etc.. do I still set the bias to .825 with those different tubes.

Yes that is correct,every time you change tubes check the bias.
