WARNING! The mosfet shown in the clean schematic in this video is wrong! It should not be a IRF540N, but rather the one mentioned in the video 2 of the series, which is a higher voltage component.

The design and build of a capacitor leakage tester to check capacitor leakage at their rated (or working) voltages in tube radio and other tube era equipment.

The linearly variable voltage implemented in the design also serves as a means of reforming old electrolytic capacitors.

I could have bought an old one and restored it, but this seemed like a better idea - designing and building a more accurate and modern one, as well as making the applied voltage linearly variable so that I can get a true reading of the leakage as the operating voltage rises.

Obviously, another requirement was safety. High voltage zaps you, and I like living.

This video is the third of the design stages of the circuit.

Have fun, and be careful - this thing has high voltages that can kill you.
