The ECL85 is purpose designed for frame generation in television receivers. The triode provides the oscillator and the pentode is optimised for pulse output operation into the magnetic load of the scanning coils.

The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 68 mm tall.
