RE: SE 6V6 triode : effect of plate to plate feedback ...

The power level for THD% measures in triode mode was just over 1/2W before onset of clipping.

I get more power in UL mode, over 1W.

The PT in this case is a bit undersized, probably better for a preamp than a stereo SE amp, so the biasing is conservative.


Edit: in SE UL mode w/fbk, Max Power Out was 1.67W @ THD = 1.78%

Vin at max power = .74V , Voltage Gain In/Out = 5

In SE UL without feedback @ 1W power out , THD = 3.88%

I'll have to see it improved THD% with feedback = a better listening experience or not.
