O.K. I could get it... Lets see... I guess the non Horton schezmo???

I'm in a rush to get somewhere at the moment but, Is this a class AB or B or??? Just that, 70Volts on those 240s must mean realatively low bias current... those transistors seem to work very well up around 2A or so, but not at 70Volts!
I will take a look later... I have my own prototype to play with this weekend but I'll squeeze in some time...

Hello the class of this amplifier si AB

The producer recomands to use only +/-70volts but you could use more than that for highter currents output
