Designed as general purpose triodes, two independent valves exist in the ECC82 envelope. A special quality version was also produced, the E82CC. Designed for differential amplifiers in industrial equipment, the anti-microphonic and matched pair version E182CC was also made.The ECC82 is practically a pair of 6C4 in one envelope.This is a 21st century version made by JJ Electronics.An amplification factor of 17 is quoted, which is much lower than that for the pin compatible ECC83 at 100.![](../pics/abn0044a.jpg)
The anode design of this ECC82 includes a depressed centre usually found on the ECC86 and similar VHF valves.![](../pics/abn0044b.jpg)
The central screen and copper connections to the base pins.The thin glass tube envelope is 21 mm in diameter and, excluding the B9A base pins, is 49 mm tall.References: Data-sheet & 1040. Type ECC82 was first introduced in 1951. See also 1951 adverts. |
