RE: Because...

"The capacitor will get its share well before the output tube. This prevents the output from performing exactly to its drive signal and you get a shift in the operational point."

Please show me this.

I have said before, if this theory is correct we should be able to see it.

A scope on the B+ of the output transformer (while playing music) will show AC if the supply is not supplying the current that the tube wants.

I've done this with both a low capacitance, low inductance, low DRC supply and my critical supply. Both amps were SET 2a3.

The supply that you say should have been starving the output tube showed nothing.

The supply that you say should have been starving the output tube less showed a lot of AC.

It's interesting that you are concerned about starving the circuit of current but at the same time your supply has the rectifiers turned off for a good deal of the time.

Where does the current come from while the diodes are turned off?
