I bought these to swap out the stock tubes in the ART Tube MP Studio Mic Preamp.
in comparison tests on a neo 2488 (in 24 bit recording mode) using a new mxl 67g, the stock tube was precisely the same on vocals.
I did not test on anything else. So in my humble opinion, these tubes provide no more "warmth" or "presence"
for the mxl 67g using the ART Tube MP Studio Mic Preamp than the stock chinese tubes that it comes with. The upside
is that i have back up tubes if i ever need them. I didnt expect miracles. the ART Tube MP Studio Mic Preamp is a $30
preamp. But i have to admit i expected some noteable difference. Even slight. But there was none.

Simply the best by many critics besides myself for music devices but the main thing I want to say is these tubes dont light up which might confuse people that the tube is not working properly but that is how they are designed it doesnt mean there is something wrong with them you can go on other sites and they mention this, I had to learn it for myself!I want others to know!

Probably one of the better vacuum tubes I've ever toyed around with. It is very warm, and yet so clear and crisp. I would definitely recommend this to anyone.

Bought tubes for use in a Mic pre-amp, to replace O.E. tube. Price was good. replaced the burned out OE tube. The ART Mic Preamp works fine now. Had used another brand tube in the interim, butit didn't work. Would buy these again.

I bought two of these tubes to replace the Chinese tubes that came in my VHT Special 6 Ultra. The sound is sweeter with more clarity. I gave it a few hours of playing over the course of several days to get a real feel for the differences in sound. Specifically, the WA tubes are somewhat bright. I wanted preamp tubes that would let my instrument's sound come through without much coloration. Both my tubes have been in now for about 12 hours of playing and are holding up perfectly. I was a little surprised at the quality of the Chinese tubes. The stock tubes lasted through around 50 hours of various styles of playing without failure. If you're on a tight budget and need to know if you've just HAVE to replace the Chinese stock tubes, I'd recommend keeping them until they go out on you. However, if you are in the same boat as me, and wanted a little higher quality sound from your VHT amp, these are great tubes. As a side note, preamp tubes can be mixed and matched without trouble. Power tubes (el34/84 or 6V6/6L6 tubes) need to be matched and biased.

The Sovtek 12AX7WA came stock in my new Hartke LH1000 bass amp. Even after several hours of break-in it had a lot of crackle and hiss. I Almost sent the amp back but I knew the crackle sound came from the tube. Swapped it out for a Svetlana 12AX7 purchased here on Amazon. Much less noise. Zero crackle. Fairly warm sound. I'm much happier with the new tube and the amp.

Been using 3 in my Fender Blues Junior 15 watt practice amp for a month.
Just ordered 6 more.
In case the Russian / Ukrainian thing makes 'em hard to get.
That's how much I like 'em, and for the price ?????
No Brain-er.
