Just picked up this cool little unit, Yaqin ms-22b.riaa today. The tubes in it are 12ax7b "china". Anybody got any ideas of what to roll into this thing? Surely there must be something better out there than those.:smile:

    You can spend time and money searching for whatever rare old ax7, just order a pair of Sovtek 12ax7lps and be done with it. You don't need $200 worth of tubes in a cheap phono stage. I'm interested in how that unit performs, be sure to post impressions / comparisons.

    Cheers

    Check your lips at the door woman. Shake your hips like battleships. Yeah, all the white girls trip when I sing at Sunday service.

    I'll give those sovtek's a try. I wasn't planning on rolling in a $200.00 set of tubes, i didn't pay that much for it. I just figured there must be something better than the pedestrian/garden variety "china" tubes out there. I just got it and have not done much serious listening yet. It seems very well made on the outside, i will open it and have peek on the inside.

    I'm running the Sovtek 12ax7's in a Pro-ject Tube Box SE phono pre, and they compared very favorably to a pair of RCA clear-top, side getter tubes from the '50's that tested at 65% life left. The Sovtek's are very quiet tubes with a very nice detail and depth.
