In a PP stage, 350Vrms from plate to plate is 250V peak from either plate to CT.

The nominal primary impedance is 8k for push-pull with 8 ohm secondary, so that is the starting point.

Both Grant Wills and Frank Hughes showed 17W clean max level in to 8 ohm resistive load with 270-300V B+ in a fixed bias, UL configuration, so that's a good start for the M1115 with 6CM5. I'm hoping to repeat that setup soon, and will try and get some power-bandwidth and distortion info for both non-UL and UL configuration.
