The PL509 was one of the last TV line timebase output pentode valves to be designed.

The PL519 replaced the PL509 and was pin compatible. These valves were designed for service in colour television receivers employing shadow mask tubes.

The EL509 differs only in heater requirements.

The normal anode voltage of 160 Volts is designed to be exceeded by pulses of up to 8,000 Volts and 1.4 Amps.

 

Radio amateurs also used such valves, known in America as ‘sweep tubes’ for short-wave transmitters, sometimes with the valves in parallel to increase the power available.
