The ECL82 is an audio triode plus output pentode. The ECL82 was much used in record players with crystal pickups of the late 1950s and early 1960s. Crystal pickups had a relatively high output and when coupled with the single ended pentode output stage made effectively a single valve design. Only a rectifier was required to complete the line-up.
See alsoECL82, PCL82 and UCL82.
The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins the valve is 68 mm long.
