The plate voltages should be fine so long as the sinewave out of each is equal in voltage and the output of the 6L6 tubes distorts before the previous stage.

A person on the diyaudio forum told me that he had tested 6SN7 tubes and found significant variations, with some very much unbalanced.

I got it playing nicely now, with 6L6GB tubes. I sounds great playing an FM jazz station. I can hear all of the instruments. I'll replace those with new production 6L6GC tubes tubes tomorrow.

Here is the schematic:
