High-Power Balanced Tuner
balanced-tuner is very simple; three components! For a homebrew project it

a relay to select two pairs of coil taps and a vacuum variable capacitor.
assembly using .063 aluminum sheet, 1/4 x 1/4 square stock drilled & tapped.
The rails are offset by 1/8 for the lucite cover to be added.
chassis construction with 1/4 x 1/4 square stock and angle stock.
