This 6DJ8 was obtained from a Tektronix oscilloscope 'Y' amplifier. The design is ruggedly constructed and the 6DJ8 is the American designation.The valve is a pair of screened triodes. They are low voltage and low impedance, used for wideband amplification in the oscilloscope but originally designed for VHF front ends where they were designed to operate as a cascode amplifier just as the earlier PCC84.Although not designed for the purpose the equivalent ECC88 has latterly found favour with builders of high performance audio amplifiers.The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 46 mm tall.References: Data-sheet & 1040. Type 6DJ8 was first introduced in 1957. See also 1957 adverts. |
