This valve is a version of the famous 807 transmitting tube, developed in WW II from the 6L6G valve. It was used as the RF final stage in medium power transmitters. It was also used as an RF driver stage and in push-pull modulating amplifiers. It was popular with Hi-Fi addicts and Amateur Radio operators, as it had a top cap anode connection, and could have a high voltage applied to the plate, up to 750 Volts. It could deliver up to 120 watts of audio power in a suitable push-pull circuit (class AB2), or 75 Watts of RF power (one valve).
