The ECL86 was one of the last triode plus output pentode valves designed and was released to the market in 1962. Uses were in domestic radio and audio equipment. Normally in single ended output stages for radio-grams and tape recorders. The design proved popular in low cost stereo systems. The ECL86 was preceded by the ECL82.
This exhibit is my spare for the TK14 tape recorder that I have had since December 1963.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 72 mm tall.
References: Datasheet & 1040. Type ECL86 was first introduced in 1961.
