I make my own AC to solve that problem

.

At first I had problems with bias drifting along with the line voltage drifts. I am using stacked supplies so when B+ drifts with the line voltage the bias drifts.

Solution, use an AC regenerator. I bought a Crown pro audio 600W amp on sale, a low distortion sine wave generator, and a 3:1 power transformer hooked up backwards to the speaker outputs on the Crown to get a very stable, very clean, 120VAC. Added benefit you can control B+ and play with varying the input frequency.

I know there are off the shelf solutions but that's no fun and more expensive.

Oh, I can't generate enough juice to run the filaments too so they run off their own transformers hooked to the wall, not the regenrator.
