The 7C5 is an audio output beam tetrode. The figures given are for single ended use with an anode load of 5,000 Ohms.Brimar's data sheet gives the operating parameters as identical to the 6BW6. The latter is on a B9A base. The origin of the design is the RCA 6V6 originally on an IO base and introduced in the mid 1930s.For push-pull use with anode voltages of 285 Volts and anode current of 35 mA the power out is 14 Watts in class AB1 with an anode to anode load of 8,000 Ohms.The wide glass tube envelope is 28 mm in diameter and, excluding the B8B base pins, is 62 mm tall.References: Data-sheet & 1040. Type 7C5 was first introduced in 1939. See also 1939 adverts. |
