Correct... If I wanted to do the "brown sound" I'd have to use 2 separate flybacks and control circuits with one being a fixed 12.6 VDC to all of the filaments as you mention, as well as a fixed B+ for the preamp sections. The voltage to the filaments should remain the same as the Push-Pull power st...

Thanks for that info... That then comes to 6 Watts or so at "Idle" (I assume that the PP current at idle is the static current used to avoid crossover distortion {aka fixed "bias" setting}... Full load total MAs drawn would be great to know. Since we are at maybe 12 Watts total, my thoughts are a sm...

Has anyone measured the actual current draw from the main rectified 230 VDC bus? I see that it is fused at 125MA, however I'd appreciate the actual current draw at idle and full power output. The 12.6 VAC series-wired filament load is easy: 3*150MA = 450MA. This may be considered a travesty, but I w...
