Voltage Radio Detector Converter ·Pentode

5HZ6

High-transconductance dual-control pentode designed as an FM sound detector in color and black-and-white television receivers. Its two independent control grids provide specialized detector and amplifier action with considerably greater signal capability than earlier detector pentodes.
