The 6AM6 is a high gain, high impedance, sharp cut-off, screened pentode. It could be used from AF to VHF up to about 200 MHz and was found in large numbers in most types of electronic equipment. In radio it was used for RF and IF amplification, for oscillators and frequency multipliers. In television receivers it could be found in the IF amplifier as well as numerous other signal processing stages.
The anode is divided into two small plates either side of the central structure. The three wire grids pass flat in front of the anode plates.
Looking into one side of the anode with the grids beyond. The anode is a composite and not stamped out of a single sheet.
The thin glass tube envelope is 17 mm in diameter and, excluding the B7G base pins, is 44 mm tall.
References: Data-sheet, 1043 & 1040 Type 6AM6 was first introduced in 1947. See also 1947 adverts.
