From EH: "High quality 6SN7 vacuum tubes have virtually disappeared... until now. The 6SN7EH preamp tube is a beautiful sounding tube, on par with RCA's red base 5692 tube. It maintains a linear response while being able to accept a full voltage. Vintage tube amp users and audiophiles will be thrilled to find that a superior quality, ultra low noise replacement 6SN7 tube finally exists." Other Electro-Harmonix tubes6SN7 Tube Types

Electro-Harmonix 6SN7EH | Maybe a bad unit.

by -

The EH-6SN7 tube has a terrible buzz mostly on the left channel. I have to use headphone with high impedance rating.

Electro-Harmonix 6SN7EH | Worth every cent I paid, overall tone is very very pleasing

by -

Worth every cent I paid for. Before I forget the low shipping price (before the covid19) was a clear incentive for me to buy. OK, the quad of this EH-6SN7 tube, is on the overall well integrated. The bass noticeably palpable (not bruce lee punchy), and the highs are expressively controlled (can be a little more extended). But the overall tone is very very pleasing, nothing jumps out disproportionately. BTW, I used it on my Schiit Freya+ Preamp.

These EH-6SN7 tubes sound phenomenal, mind you my ears are use to solid state amps, just got the Darkvoice, and have jumped in to this tube rolling thing recently. The Tung-Sol I grabbed from here sound great too...but these, the Electro-Harmonix... wow, so open and spacious, and clear, everything feels tighter, faster, so good this tube.
