The ECC83 high impedance amplifier triode was designed specifically for audio use and has a high amplification factor of 100.This valve was made in the GDR (German Democratic Republic) or Communist East Germany. The valve envelope is a wider tube than UK manufacturers used. The bright strut visible in the centre of the image is the support for the getter holder ring.
The anodes are formed from a sheet that is carbonised to form a better radiator and is folded at one end and the joined end is left as a flat wing to form the fixing and an additional radiating fin beyond the three holes.The thin glass tube envelope is 21.5 mm in diameter and, excluding the B9A base pins, is 47 mm tall.References: Data-sheet, 3002 & 1040. Type ECC83 was first introduced in 1954. See also 1954 adverts. |
