  • Great sounding tube

  • Matched Pair (2 tubes)

The Mullard 12AU7/ECC82 reissue is a great 12AU7 tube. This tube has low noise and low microphonics. A great tube for Hi-Fi amps and microphones.

Don’t know if I got a bad example, but I had to return them because my Rogue Sphinx v2 far preferred JJ EEC802s or 1960’s nos RCA tubes. One channel seemed to drop the signal a time or two and when working, they seemed to have a raspy edge on some voices. Dunno, but for the price, not taking the chance to keep trying to love them.

These tubes are very good! I use these in my vintage Dynakit/Dynaco ST70 tube power amp, in combination with Mullard EL34's and a Mullard rectifier tube. I find that my amp sounds better, and is quieter in terms of hiss/buzz/noise, than with other tubes and I've tried a lot of them. The Mullards give a nice balanced sound with beautiful mids and treble and decent bass. In my case I pair my tube amp with a small subwoofer to get the low end I like. Recommended!

I have an XDUOO TA-22 which I love. I have three sets of tubes for it and these are the most expensive and probably sound the best.The stock tubes were just fine, but a tad bright/clean for me. I like a bit of a stronger bass/sub-bass and a bit of a warm sound. I put these in and let them "warm up" for about 80 hours before I wrote this.The tubes provide a nice texture to the music and seem to fill in the bass/sub-bass just fine. The overall "warmth" of the sound seemed to be there. I listen to all kinds of music but mostly "Classic Rock" and, I feel Classic Rock on a tube amp is just **kiss*.Overall the tubes are an upgrade to the stock tubes and sound good to me. Worth the price in my book.

Running these in a Rogue Sphinx 1 and they sound excellent over the stock tubes out of the box. Tried out the Golden Lions at double the price of these, and not only sounded clinical and lifeless, but also lost a little gain. These are the ones you want. Don't bother with the rest.

I ordered these and they were shutting down my system. I returned them, but it was my fault. Someone had swapped tubes in my preamp and changed the voltage to 6V. I'm sure they are great tubes and wish I had figured out the voltage settings before I returned them.

I was happy with these over the stock ta22 xduoo tubes until I bought the Apos Ray tubes.

12AX7の球転がしでKT88と同時期に購入しましたが、音痴の自分には余り判りません、ネット観てると実際本当に判って記載してるのかなと思う今日この頃で、TRK-3488もキット購入、現在オブションの抵抗も無き為、実装の物で組ました恐らく、実装の状態が真空管AMPもベストかなと思います。

たまたま古いオリジナルMullardの12AU7を持っている(プリアンプEAR834Lで使用)。確かに、わびさび、優美さでは新しいコピー版は負けるが、解像度や明瞭度では上。ロックやジャズを聴くなら、コピー版の方がいいと思いました。

Terrific buy. Purchased for my Rogue Sphinx V3. Was glad to see other owners in the comment section and their positive experience with these tubes. Ran the stock tube for a year and the sounded great. Then got some elevated rush from one of them and contacted Rogue and got some RCA Cleartops as a premium upgrade/replacement. Really liked their sound as well but had far better soundstage and upper end clarity. From there decided to try some others for the fun of it. Even my wife commented on the sound improvement. The Mullards really shine. Came beautifully packed with a matched pair of Tong-sols as well that I have yet to try. I would highly recommend to anyone new or experienced with “rolling”.

Tubes do sound different . If you are looking for a vintage, creamy, 70s style tube tone with a fat, warm midrange and bass then these are great. If you are looking for a more bright sound with clinical clarity and a sparkling high end then I suggest you try something else. Reviewed using a Rogue Sphinx V1 integrated amp, JBL 530 speakers via Kimber Kables playing both analog and digital sources. MMF 5 turntable w/ Gold ring cartridge and LPs , Music Hall CD player and streaming through Audio Engine B1. Enjoy !
