6N1P-VI (original box)

The 6N1P-VI 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.

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

V – tube with increased reliability and mechanical strength;
I – tube designed to operate in a pulsed mode.
