I’d take a close look at the control grid drive to the 6V6s, and compare
it’s peak amplitude to the headroom you have on the phase inverter. You
may find that the phase inverter isn’t driving one of the 6V6s fully into
saturation. In other words, the phase inverter runs out of dynamic range
and clips before the 6V6. This is a known problem with those amps. I’ve
fixed it by giving the phase inverter more B+ voltage to work with. I
move the phase inverter’s supply lead up one notch on the power supply
voltage divider. Problem solved.
