6N1P-EV (original box)

Description

The 6N1P-EV is a long life miniature 9-pin medium gain dual triode vacuum tube used as a line audio amplifier and cathode driver. Each tube contains 1.408 mg of gold.

Except for higher heater current, it’s a direct plug-in replacement for the 6DJ8, ECC88 and 6922.

Russian 6N1P-EV feature very low distortion, medium transconductance, higher plate voltage and dissipation rating than 6DJ8. Internally shielded between sections, 6N1P-EV can be perfectly used at differing signal levels. A larger cathode than 6DJ8 types gives 6N1P-EV longer life and more transient current capability.

Equivalent to the 6DJ8, ECC88, 6922

E – the letter characterizing the increased durability of the tube
