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

PCH200

Series-heater triode-hexode developed specifically for television synchronization and pulse-processing circuits. The hexode performs noise-gated sync separation while the high-transconductance triode provides a separate fast amplifier or pulse-processing stage.
