Heater-cathode type used as af power amplifier and modulator and as rf power amplifier and oscillator. May be used with full input up to 60 MHz. For class C telegraphy operation at 80 MHz,
plate voltage and input should be reduced to 80 % of maximum ratings; at 125 MHz to 55 %. Class C telegraphy maximum plate dissapation, CCS 25 Watts, ICAS 30 Watts.
Requires small 5-contact socket and may be operated in any position. Plate shows no color when tube is operated at maximum CCS or ICAS ratings.
