Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Triode

6066

Ruggedized double-diode high-mu triode combining detector or discriminator functions with voltage amplification. The paired diodes provide signal and control-voltage rectification while the triode supplies substantial gain for communications and receiving equipment.
