Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Triode
Double-diode high-mu triode combining detector functions with voltage amplification. Two independent diodes provide low-current signal rectification while the triode supplies substantial subsequent receiver gain.
High-gain audio triode combined with twin detector diodes.
Miniature 7-contact
