Better to have a 100k linear stereo potentiometer with the two extremes connected to the two feedback voltage dividers and the wiper to driver's g1?
This way it becomes possible to blend between the two feedbacks (even if it will be a bit scratchy due to the different voltages of the two voltage dividers).
Anyone has experience with Solen Fast 10 uF / 630 V / MKP for bootstrap?
I will parallel a 100n to it.

Another idea for the driver (for SE and PP). I will test it the following week.
1,1 Vrms at its input gives 135 Vrms on its output with 1,7% THD. Idle plate current is 8,3 mA.
100 Vpp is given with 0,3% THD. Always 2nd harmonic dominant.
As for the UNSET, it can be used for Fet, Mosfet and cascoded triodes as well.
