The General Radio 1205-B Variable Power Supply was introduced in Catalog P (1959) and remained available through Catalog S (1965).

It is a general-purpose, variable power supply having three outputs; high voltage, bias supply and heater. The high voltage is regulated and continuously variable up to 300 V at 200 mA, the fixed bias supply provides –150 V at 5 mA maximum. The heater supply is capable of 6.3 V/10 A or 12.6 V/5 A.

The rear cover is fitted with a cooling fan with spring contacts to simplify service. Unit instruments connect to the 1205-B through a connector on the right side of the instrument.
