The 6GV8 (also marked as 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.
Zaerix were importers and resellers and this valve is clearly marked as a product of the USSR.
The ECL85 indicates direct equivalence to the 6GV8 design.
The small triode on the left with an electrostatic screen betweens the triode and pentode. The latter looks to actually be a beam tetrode. The pentode cathode is rectangular with the heater passing through it six times.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 68 mm tall.
