High-Power Balanced Tuner

A balanced-tuner is very simple; three components! For a homebrew project it is great
fun to "fancy it up" a bit. In my case, I added forward and reflected power meters,
a relay to select two pairs of coil taps and a vacuum variable capacitor.

Chassis 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.
