I got a T2 and it started with a Carbon LOL!

Quit slacking, you need to be building the circlotron, the upgradeitis is too strong!

All real stats amps float 900v at least.

Sure thing. My T2 is original from KG design and chassis. This chassis was from @georgep last run

I always get a warm fuzzy feeling when I see people enjoying their T2 - almost makes me forget how painful and time consuming (and expensive) it was to set up the chassis group buy.

How regularly do you check bias of your tubes? Do you re-bias each time you roll a different quad of EL34s?

As long as tubes are reasonably balanced (mainly the input tubes), you will never have to adjust anything regardless of how many times you swap tubes. Also the T2 isn't adjusted the same way as other Stax amps or the BHSE (which people should also likely not need to adjust but seem to want to do it anyway). Just use good tubes from reputable sources and the voltages wont change.

Thanks for the clarification, George. With the BHSE, is it also unnecessary to bias each time one rolls a fresh set of tubes?
