The General Radio 1206-B Unit Amplifier was introduced in Catalog N (1954) and remained available through Catalog S (1965).
The Type 1206-B is a unit style general purpose amplifier at frequencies up to 500 kHz. The recommended power supplies are the Types 1201-A, 1203-B and 1204-B (adjusted to 300 V). The 1206-B can deliver 3 watts of output power with reduced frequency response, 1.5 watts with excellent audio response. With low hum and hi gain its well suited for audio and ultrasonic laboratory use.
