Description

T-12BH7A-RCA Vacuum Tube, 12BH7A, RCA, Triode, Dual, Medium MU

New-Old-Stock (NOS) tube.

RCA brand

The 12BH7-A is a miniature, medium-mu twin triode designed primarily for use as a vertical-deflection amplifier in television receivers. In this application, the two sections may be employed in parallel, or they may be employed as a combined vertical-deflection amplifier and vertical oscillator. The tube is also suitable for use as the horizontal oscillator in television receivers as well as in a wide variety of general-purpose applications. Each section of the 12BH7-A features a relatively high plate current at low plate voltages and is capable of withstanding the high pulse voltages normally encountered in vertical-amplifier applications.

The 12BH7-A differs from the 12BH7 primarily by incorporating a controlled heater warm-up characteristic which makes the tube particularly suited for use in television receivers which employ 600 mA series-connected heaters.
