    RCI-2985DX voltage schematics

    That would require firmware from RCI, which I doubt you could get. Plus you would need a programmer/hardware for the HD4074818 microprocessor.

I removed the PLL IC, and checked both VCO's by applying a low voltage to each VCO, and both were working correctly. I traced it down to corrupted data coming out of the microprocessor. The data is...

    Golden Falcon 1000 (10) 8908 tube version

    Hello all, I have an old Golden Falcon (10) 8908 tube amplifier that I would love to get working, but cannot find schematics on it. Looks like someone got in there, and modified it pretty good. I am hoping that one of you guys have this amp, and could take some detailed pictures of the bottom...

    capacitor bank

    You would need approx. 40-50uF total for a 3CX3000A7 @ 2 amps plate current to stay at 3% ripple. Go here for a calculator on power supplies: Martin E. Meserve - K7MEM - Un-Regulated Power Supply Design It is best to run electrolytics at 70-80% of their maximum voltage rating of 450 volts per...
