In Reply to: tube noob... was it a good idea to balance EH-6922 posted by bullethead on January 9, 2016 at 06:14:21:
I don't think this is at all necessary in your situation. I have sat and measured random 6922's and found no more than about 1.5dB of variation between triodes. If you have resistive plate loads, this will tighten up a bit more.
Do note that if you have a properly designed differential circuit, balancing the triodes is even more unnecessary, and that 1.5dB will be wiped out by proper implementation of a current source.
In a strictly push-pull circuit, triode balancing does become useful.
