No global feedback power Jfet Circlotron
Maybe my next amplifier
bridge
The amp did not have a name yet, here it is: RAY
A small video
Sorry for the quality but it shows that the amp works

Capacitor stack
Card ready to be powered
Mosfet Circlotron PCB : Copper spacer to link capacitor stack
Last version : Mosfet Circlotron ready to made !
Simple CFA Circlotron J113 version
THD 1khz 1W 8ohm 0.000541%
THD 1khz 100W 4ohm 0.026%
Damping factor 100hz / 1khz = 8/((20.705*8)/20.656-8)= 421
Simple CFA Circlotron TO92 for voltage stage
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)
Bipolar LTP input stage with only one CCS
THD 1K 28V 4ohm (100w) 0.0027%
THD 1K 4V 8ohm (1w) 0.0001%
Need to change VAS CCS for thermal compensation.
