Thanks for the LM317 info.

The issues are high driver stage distortion and the level of odd 3rd order harmonics at the output of the amp.

I'll have to post updated graph to show this.

Maybe that is why some people either love or hate the RH circuits.

My amp does not use exact values but is the same sort of circuit.

I'm also looking at the pentode and mosfet driver stages for EL84, but I will keep listening to what I have so far to determine if I want to keep it or not.
