Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Triode
Double-diode triode combining radio detector and AVC rectification with subsequent voltage amplification. The paired diodes handle signal and control-voltage functions while the triode provides receiver audio or voltage gain.
Duplex-diode high-mu triode with two diode units and a high-mu triode sharing a common cathode.
