Preferred Series 12AX7
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..."
This 12AX7 audio tube has crimped, mid-sized plates, think mica spacers, and a disc-style getter ring.

Great tube!
by Tim -
I tried these because I really liked the 7025.. happy to say these are on par IMO. Probably a touch warmer sounding but I like that! Works well in my Orange's V1 position.
Beautiful in my Fender Blues Junior
by Jason -
I tried these in my blues Junior and I’m blown away by the beautiful difference in sound that I get from these tubes when compared to the stock groove tubes. Beautifully balanced and harmonic. Get these and don’t look back!
Fantastic 12AX7
by Don -
I’ve tried many different 12ax7 tubes in my Marshall head and the only tubes better IMO are NOS.
On a different note, the customer service at The Tube Store is top notch with very reasonable prices on tubes as well as shipping to the states (plus much faster than I would have thought). The people there are very knowledgeable regarding different amps and what your particular sound is you are after.
An absolute must for V1
by Deda M
Using this tube in my V1 position really gave a new flavour to my amp.
It’s a win with my Delta King 12
by Gary Atkins -
Replaced the stock tubes in my Supro delta king 12.
Clarity and definition is much better and there is no more flubby when driving the preamp at full volume (Master is at a low setting)
