1206-B
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 for 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, and 1.5 watts with excellent audio response. With low hum and high gain, it is well suited for audio and ultrasonic laboratory use.
