GS-35B Tube. New in Box! (2.5kW hf, vhf, power)
Seal and Envelope Temperature - 200 C. Maximum Length -177 mm Maximum Diameter -100 mm. Weight with heat sink: 2.5 kgs.
The so called "Specification Sheet" for the GS-31B/GS-35B was provided for the tubes as they were produced in the Soyus Union-engl. Factory for the Russian military and select civil aviation customers.These tubes were produced primarily for use in UHF RADAR applications. The factory was manufacturing the tube in such a manner as to guarantee their performance under the specified conditions. Use of this tube in the spectrum occupied by the amateur bands 160 meters through 70 centimeters was never specified nor measured. You can also exceed the rated anode voltage specification of 3,000 volts to as much as 4,500 volts. The majority of users are operating their amps with anode voltages between 2,500 and 3,000 Volts. They make a mistake and the grid current overload. It is better use the maximize anode voltage. Caution should also be exercised when operating the tube with filament voltages that may go below the nominal 12.6 volts. If your line voltage drops enough to cause your filament voltage to go below this level, you should adjust the filament voltage so that it will stay at or slightly above 12.6 volts under all conditions. Low filament voltage not only contributes to rapid tube failure, it will also cause your tube to have low output.
