Is likeweier on Sale? November 2026

Questions and answers

What is the 6J1P-EV tube used in likeweier's preamp module?

It is a Soviet-era high-frequency pentode, a rugged small-signal tube with good linearity and low microphonics. In this module the two tubes are wired as a headphone preamp stage rather than as a power amp.

Does the module come assembled and ready to use?

It is a bare module: a board with the tubes and circuit, not a finished headphone amp in an enclosure. You supply the chassis, input and output jacks, volume control and a 6.3V heater supply.

What power does the board need?

The heater draws 6.3V at 0.17A, and the board also needs a high-voltage plate supply for the tubes. Check the board's own markings before wiring it, since the heater and plate rails are separate.

Can I use it with low-impedance headphones?

A pentode preamp stage like this suits high-impedance headphones better than low-impedance, sensitive ones. Pair it with a separate solid-state amp if you need to drive low-impedance loads.

What is likeweier's returns policy on these modules?

Return terms come from the individual store that ships the module, not from likeweier itself. Confirm the seller's policy before ordering, and test the board as soon as it arrives.

Are there likeweier discount codes?
