Our take on the 6J1 Vacuum Tube Headphone Preamplifier Module

A pair of 6J1P-EV pentode tubes, the Soviet equivalent of EF95, 6F32 and 6AK5, sold as a drop-in module for tube preamps and headphone amps that use that pinout. The tubes are built with a gold-alloy first grid and copper lifting grid, and the maker claims a warm, low-noise sound with a wide sound field and stronger bass. They suit owners of budget tube headphone preamps who want a spare or replacement pair, not someone looking for a complete amplifier. Compared with premium NOS EF95 types, these are a low-cost way to hear a tube swap, but the sound change is subtle on most gear.

Questions and answers

Will these work in my tube headphone amp?
