    Sovtek 12AX7LPS are excellent tubes!

    My Yaqin MS-23B phono preamp sounds WAY better with these Sovtek 12AX7LPS tubes than the stock Chinese 12AX7B tubes! The mid range just comes to life. The high frequencies are more detailed, still nice and smooth sounding. Bass has more authority. Very nice 3D sound stage! Higher gain, don't have to turn the volume as high. Highly recommend the Sovtek 12AX7-LPS tubes for a phono preamp! Viva Tubes puts stickers with the test readings on each of the tubes on the box, so you know your getting a nice matched pair! Excellent service!

    Sovtek Tubes Good Value

    These are very good tubes for use in a vintage tube receiver. They are a great replacement for old vintage tubes that have lost their edge.

    Low noise short plates, as advertised.

    These sit in the preamp stage of a restored HHScott amp and helped measurably with phono hum. I've tried NOS 12AX7's in the past only to run into a noisy tube every now and again. Glad I went this route.

    They rock in a Blues Deluxe

    Just did an overhaul on a 1996 Fender Blues Deluxe using the Fromel Supreme Mod kit and these matched tubes. I could not be happier with the results, the amp sounds incredible.
