Another Class A ( BJT ) Jean Hiraga !

On the bench this day, I have a Jean Hiraga amplifier its a amplifier with 30watt RMS /8ohm output. HOWEVER mine’s a bit different. Running higher bias and dual regulated powersupply setup. Achieving 60watts RMS output @ 35V rails along with 22v super regulated front end circuit.

IN the pictures below you can see before and after pictures the red board on the side is the regulator circuit for the front end of the amplifier circuit.
