Class TD Schematic

[kartino]

Folks,

I post class TD schematic. It is based on the only famous class TD.
This is not yet trial. Layout is not yet available. I bring new idea for gate supply, and more simple design suitable for DIY audio pro enthusiast, dreamer for big muscle amp.
Sorry small mistake, R126 is not 27K. but 18K

Regards,
Kartino

TD design decoded 😀
You will understand from the PWM card. See my PDF, I put converter in one page. It is a self oscillation in a LTP. Comparing the amp out and prefilter signal.
