COOLING TECHNIQUES IN TRANSMITTER Introduction In modern A.M. transmitters power valves are used in the PA and modulator stages‚ which are condensed vapour cooled ceramic tetrodes. In the old generation transmittes‚ triodes are used in the PA‚ modulator and exciter stages. Both the tetrodes and triodes tubes are capable of being operated at high voltages (11 kV DC) and large anode current of the order of 50 Amps. They also draw large filament current of about 620 Anps at 24 volt CQK-350
