Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Diode-Triode
Series-heater triple-diode triode for AM/FM receiver detection and audio amplification. Three diode sections provide demodulation and control functions while the high-gain triode amplifies recovered audio.
Triple-diode triode for FM/AM demodulation and audio-frequency amplification.
Small-button Noval 9-contact
