The Power Supply Circuits
THE PSU
K1 / K2 - Microwave oven transformers, 2100v output.
K3 - Mid power supply transformer for Oscillator, grid bias and small tube
heaters.
K4 - 12.6v 10A Filament transformer for output tube.
C1 / C2 / C3 - Microwave oven capacitors.
D1 / D2 - Microwave oven diodes.
C4 / C5 - 470uF Smoothing Capacitors.
C6 / C7 - 0.1uF Filament Decoupling Capacitors.
R1 / R2 - 220k Bleeder Resistors.
D3 / D4 / D5 / D6 - 1N4007 Rectifier Bridge.
Yes, thats 4 large and heavy power transformers ! K1 & K2 are supplied via individual variacs so I can control the output tube parameters fully. The bleeder resistors are there for my safety while testing. Should suck a few watts when I power the beast up :-)
