The Preferred Series 7025 is a high quality 12AX7 tube type. This tube is a reproduction of the highly regarded and sought after Mullards from the 1960s.

This 7025 is a high quality and very rugged custom 12AX7 tube produced for us in China by the Shuguang factory. The plates are manufactured out of a premium metal imported from Germany and supported with extra thick mica spacers to insure against microphonics. They are burned in and tested at the factory and then again on our digital high voltage equipment to make sure the tubes selected for you will provide outstanding tone and performance.

From our review: "A great sounding 12AX7 tube type that reminds me a little more of the ECC83 that Ei made in the old days. That's a pretty nice compliment. I compared this tube against an old Ei and Telefunken smooth plate and there was very little difference. Lots of gain with a rather low noise floor. No microphonics issues at all. Very good considering the large plate size. Spot welding may be better for microphonics than crimped plates. I tried it in all the standard guitar amp duties and it was fine. Fabulous in Blackface Fender amps. We tried this 7025 in a 66 Vibrolux reverb 2x10 combo and the tones were all there. Light and shimmering or really aggressive, it's all good."

Warranty: The Preferred Series 7025 tubes carry a 6 month extended warranty.

pure tone


love it for my rivera superchamp..some other 12ax7 tubes just a little too much gain... superchamp fans this is the one

Top Notch!


Great tube! I tested this alongside a Ruby, JJ, Tung sol and a Chinese tube. All sounded good in their own way but I chose this tube to keep this in my amp.

Highly Recommended !!


I put the Preferred Series 7025 / 12AX7 in my 1996 Marshall JMP-1 pre-amp and it's really sound bad ass to me.
Compared to the original tubes, my pre-amp came alive and it's all good in any frequency range of sounds.
Excellent tubes!

Too quiet for its own good


I was looking forward to listening to this 7025 tube on my vtl 7.5 preamp but it wasnt meant to be. It was too quiet for my liking. A little on the dead side in terms of vocal openness and light footed with the low frequencies too. It may suit other systems but not mine.

Great Tubes! Great Service!
