On the right, you can see the use of the 3 different connectors for the main, control, and high voltage interconnect cables. I used only the very center pin on the 7-pin connector to carry the plate supply, providing extra isolation from other connections.

Since the meter switch is sometimes above chassis potential by as much as 380 volts, I isolated it with a plexiglass mount and an insulated panel shaft.

Note the mounting of the coolant connectors, and the RF connector mounts on the rear panel.

The RF connector mounts were made from the same aluminum bar stock, and drilled out just enough to pass a standard female type N cable connector. There is a set screw in the side of the mount to hold the connector in place.
