Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Triode
Double-diode very-high-mu triode for detector, AVC, and audio voltage-amplifier service. Two diode sections provide signal and control rectification while the triode supplies substantial subsequent voltage gain.
Duplex-diode high-mu triode combining two detector diodes with a high-gain triode amplifier.
Small 6-contact
