[Elecraft] OT - Source for Air Variable Capacitors

[ANDY DURBIN]

If you are making a home-brew loop why not make the capacitor too?    My loop works fine at 100 W input but not yet tested at 500 W.  I borrowed the capacitor design concept but the implementation details are mine.  Capacitor components are hardware store copper pipe, copper pipe couplers, and PEX tube.
