No global feedback power Jfet Circlotron
Maybe my next amplifier
Maybe my next amplifier
Sorry for the quality but it shows that the amp works
THD 1khz 1W 8ohm 0.000541%
THD 1khz 100W 4ohm 0.026%
Damping factor 100hz / 1khz = 8/((20.705*8)/20.656-8)= 421
I decrease the supply voltage on VAS to reduce dissipation to be able to use TO92
Simple current feedback like F5 or amazing circlotron (PASS)
Thanks to Joseph Norman Berry who offered me a solution for voltage stage :
