CV1076 DA41 MOV VALVE, 1930's

Power triode with Anode connection made to the top cap. The valves had carbon anodes with a dissipation of 40 Watts and were designed to work in Push-Pull pairs operating in class B. This class of audio circuit was both inexpensive and very efficient.

It was estimated that an output of 175 Watts could be obtained by a pair of DA41/2's working at an anode voltage of 1,000 Volts. Using a Thoriated filament at 7.5 volts 2.5 amps.
