Low microphonics and excellent linearity offer a musical and harmonic soundstage, making this 12AU7 tube equal to the original and a cut above the competition.

Electro-Harmonix 12AU7A / ECC82EH Gold | Clean and clear.


The EH-12AU7G added a more open natural sound to the pre section on my KT-88 stereo tube amplifier. Very open and precise.

Electro-Harmonix 12AU7A / ECC82EH Gold | Sound Good!


There is tension and the sound comes out to the front and it is the best!!!

The correspondence of the shop is also very kind and polite. thank you

Electro-Harmonix 12AU7A / ECC82EH Gold | Great sound


I have these EH-12AU7G in the front 2 slots of my Primaluna dialogue premium preamp. They have a nice top end without tizz, a smooth midrange, and punchy tight bass. A nice sounding solid tube, especially with classic rock recordings IMO. A bargain considering the the price of quality, low noise tubes.

Electro-Harmonix 12AU7A / ECC82EH Gold | Very quiet tubes

I replaced the factory installed pre-amp tubes in my PrimaLuna Prologue Premium integrated amplifier with these EH-12AU7G. The improvement was immediately noticeable. I am really impressed with how quiet these Electro-Harmonix tubes are. Also, the highs are more extended and overall transparency and clarity is improved. Very happy with this purchase.

Just put these EH-12AU7G into my Copland CTA 301 and wow they're fantastic. I could not be happier. Perhaps there are better tubes out there but these guys sound great.
