1201-C

The General Radio 1201-C Unit Regulated Power Supply was available in Catalog S (1965) only. It is an upgraded version of the 1201-B featuring a hybrid design with a transistorized regulator, and a zener diode replacing the voltage reference tube.

The 300 V output is regulated, the heater supply is unregulated. Both power supplies are isolated from ground.

With its five-pin power connector located on the right side panel, the 1201-C is compatible with most unit instruments.
