Description

Air-cooled 1.5 kW transmitting triode for AF or RF power amplification and oscillator service up to 30 MHz, especially industrial RF-heating and ultrasonic equipment. Directly heated tungsten cathode; the anode forms part of the envelope and carries a forced-air radiator. Explicit co-designation of RD15XA printed in the approved source.
