6N23P-EV (original box)

The 6N23P-EV tube – universal double triode with separate cathodes and low noise level. Designed to work as a broadband amplifier and high-frequency mixer in circuits of low-power amplifiers and pulse generators. Works in any position. Base 9-pin.

Full analogue: E88CC, 6922, 6DJ8 close equivalent: ECC88, PCC88, UCC88 E188CC

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