THIS IS A COMPLETE AMPLIFIER WITH POWER SUPPLY AND LOW PASS FILTER. 1.5KW OUTPUT TYPICAL. YOU CAN SEE AND HEAR THE AMP IN OPERATION ON MY YOUTUBE CHANNEL.
I HAVE BEEN TESTING THE AMP WITH GREAT RESULTS! THE 50VDC POWER SUPPLY COOLING FANS ARE A LITTLE NOISY.
IT WAS A GREAT PROJECT AND WORKED OUT VERY NICELY. ALWAYS USE THERMISTORS IN THE BIAS CIRCUIT.
I BUILT A SECOND AMP AND MADE A FEW IMPROVEMENTS. I NOW MAKE THE COPPER HEAT SPREADER THE ENTIRE LENGTH OF THE HEAT SINK. BEST TO GET AS MUCH HEAT AWAY AS QUICKLY AS POSSIBLE.
