Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Triode
Receiving tube combining radio signal detection or control-voltage rectification with associated voltage amplification. Its detector function is integral to receiver signal processing and supports classification within the radio detector/converter family.
6BT6 is a DualDiodeTriode device. Combined double-diode detector and triode voltage amplifier.
Miniature 7-contact
