Thanks for the reminder X.
In preparation for that mod, I left the one leg of the 10R resistor long and bent it into a loop under the board to make a solid anchor point for the C104 GND wire

Great designs there, JPS64. Pretty much a complete Class A solution for any amp.

Hi JP,
Very nice universal design.
Do you have an alternative heatsink to use for the rectifier board? If it’s the same heatsink as your F6 psu design, I don’t think we can’t source it in the USA.

Regards,
Vunce
