Voltage - Triode (with diode, heptode or hexode) ·Hexode-Triode
100 mA series-heater triode-hexode frequency changer for transformerless superheterodyne receivers. The triode serves as RF oscillator while the hexode performs mixer action.
Variable-mu triode-heptode frequency changer for series-heater receiver service, combining oscillator and mixer sections.
Loctal 8-contact
