Our take on the 2Pcs Vacuum Tube Headphone Preamplifier Module 6.3V 0.17A HF 6J1P-EV High Frequency Pentode Tube Vacuum Tube Headphone Preamp

A pair of 6J1P-EV high-frequency pentode tubes in a small glass envelope, 15x15x45 mm, run at 6.3V and 0.17A on the heater. They are the Russian equivalent of EF95, 6F32 and 6AK5, so they drop into gear built for those types. Buyers use them as spares or swaps in tube headphone preamps and small amps to warm up the sound. They are a component, not a finished preamp, and the two-tube pack suits anyone servicing or retuning existing tube gear.

Questions and answers

Is this a preamp or just the tubes?
Just the tubes. It is a two-pack of 6J1P-EV pentode tubes; you need an existing preamp or amp circuit to use them.
Which tubes can these replace?
The 6J1P is equivalent to EF95, 6F32 and 6AK5. Check your gear's specified type before swapping, since a wrong type can damage the tube.
What heater voltage do they need?
6.3V at 0.17A on the filament. The screen and anode figures in the spec are 120V, so they suit circuits designed for those operating points.
Will they change the sound of my amp?
The maker claims a warmer, cleaner tone with wider soundstage and stronger bass. That depends on the host circuit, so treat it as a voicing tweak rather than a guaranteed upgrade.
Are the two tubes matched?
No matching or test data is stated. If your circuit needs a balanced pair, measure them yourself or buy from a seller who matches.
