Power - TV Vertical Output ·Triode-Triode

6CM7

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.
