From our review: "This 12AX7 is a versatile, quiet tube that will be at home in just about anyone's guitar or HIFI amplifier. In a Fender Champ they displayed no microphonics or rattling, and had a warm, smooth character that can still get rowdy when driven. The detail is all there as well..."

Preferred Series 12AX7 | Great in tube DAC
by Denny L -
Wow - I ordered these Preferred Series 12AX7 online on a Monday morning, and they arrived that Wednesday afternoon. Great service TubeStore!
There were already a few pairs of the previous preferred series 7025 tubes in my stash. Those sound smooth, detailed, very musical and are still going strong after many years of service. However, I recently acquired a Jolida FX Tube DAC II for a song and have been rolling in other 12AX7's from the stash, finally settling on the above mentioned 7025's.
These ps-12AX7's sound similar but with a bit more drive, as you'd expect. They are quieter and seem to be a touch livelier and engaging, while retaining the 7025's other musical attributes.
I'm very pleased with these ps tubes. There's not a trace of hardness or glassiness as with some new production tubes. Highly recommended! Now if the TubeStore can only come up with a ps 12au7...?
Preferred Series 12AX7 | Wow!

Just bought two of these PS-12AX7 to try in some noisy amps. In two Crate V50 amps (I have 4) I put these in tube 1 position. On the first amp after putting it in I thought it was dead because until I turned up my guitar I did not hear noise. Wow! I have been using JJ's and have been very happy. These Preferred Series 12AX7 sound better midrange, top end and sustain. In the second amp same results. I have 32 amps so I will need more to try.
Preferred Series 12AX7 | A step up from JJ's

Replaced JJ's with these Preferred Series 12AX7 preamp tubes. JJ's are reliable but kinda sterile. These PS-12AX7 tubes have tighter bottom end. Better sound overall.
Preferred Series 12AX7 | Better than I Expected

Ordered the matched set of these PS-12AX7 for my Fender Bassbreaker 007 that came with Groove Tubes vacuum tubes and I'm super impressed. The GT's are lifeless compared to the PS's! Nice tight bottom end with no flub solid mids and clear articulate highs. Ordered them on Thursday morning and received them at noon the next day here in the southern US. Highly recommend TheTubeStore if your in need of fast shipping and Quality Service.
Preferred Series 12AX7 | A Quality Set Of Preamp Tubes.

Just swapped 3 of these Preferred Series 12ax7 tubes in place of Tung-Sols. The Tung-Sol 12ax7 tubes were bright sounding and I detected some “spikiness” at times in my Orange Dark Terror. Both brands have superb lows, but the Preferred Series were smoother at handling the highs. I don't play Metal music which the Dark Terror can achieve, but for Classic Rock and Zeppelin type gain, these Preferred Series work ideally.
