The 6K7 is a variable-μ voltage amplifier pentode and was designed for RF and IF amplifiers in 'modern' superhet type receivers employing AGC circuitry. It dates to the mid 1930s.It is high impedance allowing for a high Q in the tuned anode circuit.The reverse of the steel shell has a printed Type designation.The thin metal envelope is 25 mm in diameter and, excluding the IO base pins, is 62 mm tall.References: Data-sheet & 1040. Type 6K7 was first introduced in 1936. See also 1936 adverts. |
