6P14P-EV (original box)

The output pentode 6P14P-EV is used in the output single-cycle and push-pull circuits of low-frequency receivers and amplifiers. Designed to amplify low-frequency power in general-purpose radio-electronic equipment.

Equivalent to tubes: EL84, 6BQ5

E – characterizes the increased durability of the tube
V – tube with increased reliability and mechanical strength.
