Sovtek 12AX7LPS Vacuum Tube
Sovtek 12AX7LPS Vacuum Tube is rated 4.75 out of 5 by 12.
Rated 5 out of 5 by from ExcellentI'm a New Old Stock nut, but was very pleasantly surprised by the LPS. And they are much cheaper than a good NOS tube. This tube is even, warm, and expressive. I can't find much wrong with it really. It's not flimsy or sculpted, as I've come to expect from new production tubes. Works great in my guitar amps. You hear the amp without colouration. Lively, but not harsh. Also more critically, it's sounds really good in my microphone preamp too. Very unusual for any tube to be this flexible. Maybe old Mullards can pull that off. Sounds great anywhere, as far as I can see.

Rated 5 out of 5 by from Great PI for Egnater Rebel 30Worked exactly like I had hoped for my Rebel 30 in the V5 position. Little pricey, but it was basically half price once I figured in that I needed it to get to $99

Rated 4 out of 5 by from good value good soundThese babies sound very nice! A little cheaper thatn the Electro harmonix (gold Pin)and similar quality (i still think tubes in general should be cheaper). I replaced the stock ART tube in a mic preamp with this guy and the sound is night and day as far as I am concerned.Again, no features, thus the 3 rating on that option.

Rated 5 out of 5 by from Great Tube!I have tried several different manufactures 12AX7 / 7025 tubes with varying results in my Boogie. However my search stopped with the 12AX7LPS. All 3 channels improved dramatically. When matched with a set of JJ power tubes you could actually hear the Glass tube sound resonating from the speakers. Highly recommended!

Rated 5 out of 5 by from My 12AX7 of choice.I use these tubes in a 18watt handwired copy of a hot rodded Marshall 1974x, a Mesa DC-2, Mesa Nomad 100 and an ADA MP-2. They are warm, well rounded and rich in harmonic structure. The amount of noise is minimal for the amount of usable gain you get out of them. They really shine if you are looking for high definition with a natural warmth that I havent been able to duplicate with any other tubes. They are a bit pricier, but, my opinion, WELL worth the extra funds!

Rated 5 out of 5 by from Marantz 7C preamp and Sovtek LPSNo need to search for old NOS tubes. These Sovtek LPS are musical, quiet, about as good as it gets to my ear. Improved imaging, stability in my ancient Marantz 7C. True hi fi reproduction of upper harmonics. They take 10 - 20 hours to break in so don't feel disappointed at first listen - they sound somewhat cold and dead - clinical - initially. But, in a few hours the sound warms up. Hey, after all, the Russians KNOW serious music!
