ID = 49713
United States of America (USA)
Brand: Common type USA tube/semicond.
Developer: General Electric Co. (GE); Bridgeport CT, Syracuse NY 
Tube type:  CW-magnetron 
Identical to 5J33 = ZP676

Was used by Radar
Filament Vf 2.2 Volts / If 35 Ampere / Direct

External magnet, single-ended CW magnetron. Neutrode 3-section anode structure, the central one being connected to the mid point, the voltage node, of the internal loop. This three-electrode structure originated a new family o multi-segment magnetrons, referred to as 'tropotrons' by RCA, in which the internal section of the resonating line makes complete loops around the anode structure.

750 to 1150MHz operating frequency, depending upon the resonating lines

200 W min CW out. 1500 gauss

400 mA max at 1800V, 40% efficiency.

GE 'Confidential' type for use in radar jammers.
Known productions by General Electric and by ITT Federal Radio.
