  • Specifications

The 6AH4GT is an octal-base power triode housed in a tubular T-9 glass envelope. Designed primarily for vertical deflection amplifier service in television receivers, it features high perveance, low plate resistance, and high peak pulse voltage ratings. Due to its clean triode linearity and power handling, it is also popular among audio builders as a single-ended or push-pull audio driver and output tube. Operates on a 6.3V heater and fits standard 8-pin octal sockets. Available NOS and tested used.
