My 6c33c se, originally 6j4p drives 6c33c, recently modded to using Siemens D3a triode strapped, with 980 ohm output cow from Look-T.

But my fav mod is indeed the installing of multi-turn bias pot on the outside with probe test points, whereas in the past i have to turn the amp upside down with bottom off and the bias switch pot is a very unprecise single turn version. This makes now "monitoring" the bias much easier.

Yes you are correct, the Duracell are there to provide the bias of the D3a driver

Good thing about Battery Bias is i have one more thing to mess around: Battery Rolling haha. Tried Duracell Alkaline, Energizer Lithium, Ever-Ready Carbon-Zinc. Alkaline has a mechanical tone with vocal, Ever-Ready brings the humanity back :))
