RE: e80cc operating points in SRPP

Ok, I'll leave the negative feedback there. I do have enough gain using a 3k3 resistor (and 330pf) for the neg feedback loop. Not sure how much Nf I need, or how to calculate, but based on volume it seems to be 6 db or so...

I would like to keep the SRPP... I have this belief that it will sound better and be simpler than changing to cascode.

also- I threw out the bypass-less SRPP idea after calculating the gain. With the bypass it seems to be 15v of gain, and without it calculates to 2.5v...

Also calculated that makes sense to leave the current totem resistors there, and add a 1k at the top anode. And increase the voltage to 475... and increase the heater elevation to 122...
