Half-Wave Rectifier
The 1B3GT / 1G3GT Vacuum tube is a glass octal type used
in high-voltage, low-current
applications such as the rectifier in high-voltage,
RF-operated power supplies for the kinescope, or as a
rectifier of high-voltage pulses produced in the
scanning system for the kinescope. They require an octal
socket and may be operated in any position. Internal
connections are made to pins 1, 3, 5, and 7 which should
not be used.
