|The ML-5682 is a general-purpose high-power triode suitable for use in AM, FM and TV broadcasting, dielectric and induction heating, pulse modulation and similar applications. This tube features rugged coaxial construction with high-dissipation, low-inductance rf terminals. The cathode consists of sturdy, stress-free, thoriated-tungsten filaments. This tube is suitable for cavity operation and its low plate impedance adapts it to broad-band service.
The ML-5682 is water-cooled and accepts a quick-change water-jacket coupling. The heavy-wall anode will dissipate up to 140 kW with a water flow of 60 gpm. The maximum CW plate-voltage rating of 16 kV applies at frequencies up to 30 Mc. The tube may be operated up to 88 Mc with a reduction in ratings. In pulse service the tube is capable of switching up to 8 Mw with plate voltages up to 35 kV.
The ML-5682 is also available with envelope construction utilizing ceramic instead of glass. This version, designated as the ML-5682K, is electrically identical to the ML-5682.
