Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Triode
Double-diode triode combining receiver detection and control-voltage rectification with audio-frequency voltage amplification. Paired diodes handle detector and AVC functions while the triode amplifies the recovered audio signal.
Double-diode triode for detector, AVC, and audio-frequency amplifier service.
European 8-pin side-contact base
