LM317T Voltage Regulator with Pass Transistor

This Amplifier has lots of new parts and upgraded options installed. Including new Power capacitors and Transistors. All electrolytic caps on both audio boards were replaced with Nichicon Muse capacitors. New OPAMP IC's installed. New voltage regulator and signal diodes, Gold plated RCA sockets fitted along with new Speaker binding posts too. All parts were tested for more than 5% variation and any parts that had varied was replaced. We then completely rewired the DC Power and Audio output sections with silver-plated wire. The unit sounds fantastic and should be good for the next 30+ years.
