6S4P-EV

Description

The 6S4P-EV tube – high-frequency, low-noise, high-durability, low-noise triode.
Designed to operate in the input stages of high-frequency amplifiers in circuits with a grounded cathode. Works in any position.
Base 9-pin.

Equivalent to tubes: EC86, PC86. Close analogue of the WE417A tube.

E – the letter characterizing the increased durability of the tube
V – tube with increased reliability and mechanical strength
