    Tube neophyte, so reader beware. I recently entered the world of tubes with a Yaqin MS-12B preamp for my Rega P2 stock TT. After spending 20 hours listening to the stock Chinese tubes, I put the Mullards Ax7 and Au7’s in. The sound improvement was very noticeable. The mullards offerred a much more detailed sound. Crimson & Clover sounded flat until I put in the mullards to fully appreciate the song on my modest system.

    This is my favorite new production tube! I’m running this in my Silverface Champ and it’s the closest to the JAN tube that was in it when I bought it.

    I used these in a JTM45 in V1 and V2, very nice sounding pre amp tubes, lots of growl.
