Mullard 12AX7 / ECC83
Price of NOS 12AX7s got you down? This new re-issue of the famous Mullard 12AX7 made in Russia is the answer to your woes! Very low noise and microphony make this tube an excellent candidate for many touchy preamps and phonostage applications. Has a smoother midrange similar to NOS Mullards (though not quite the same). Some folks have reported them to be a smidge relaxed on top. If you want something with a little more lively presentation, try the new production Tung-Sol 12AX7.
A quick note on this tube: The filaments on these tubes are almost completely encased in the plate structure. So if you don’t see them glowing as bright as some of your other 12AX7s… don’t sweat it. It’s normal for this tube.
