Medium-Mu Twin Triode
The 6C8G Vacuum tube is a glass octal type used as a
voltage amplifier and phase inverter in radio equipment.
When this type is used in a high-gain amplifier, hum may
be reduced or eliminated by grounding pin 7 or by
grounding the arm of a 100-to-500-ohm potentiometer
across the heater terminals. This tube requires an octal
socket.
