Power - TV Vertical Output ·Triode-Triode
Dual triode intended for television vertical-deflection service, combining oscillator/driver and power-output functions where applicable. Manufacturer data emphasize vertical-sweep operation, pulse-voltage capability, and the stronger section’s current and dissipation requirements.
Dissimilar medium-mu dual triode used as combined vertical-deflection oscillator and vertical-deflection amplifier in television receivers.
