The CV2523 is a double triode with special properties. The AC anode resistance is very low at 280 Ohms and the mutual conductance is considerable at 7.5 mA/V. The suggested cathode bias resistor is given as 250 Ohms.This valve could be used in low voltage power supplies as a series pass device or it could be used for a direct drive audio amplifier. It would be useful to know its exact design use. The literature gives a single ended audio amplifier as its use.The classic envelope is 46 mm in diameter, and excluding the IO base pins, is 105 mm tall.References: Data-sheet & 4040. Type CV2523 was first introduced in 1946. See also 1946 adverts. |
