Preferred Series 7025 / 12AX7 Preamp Vacuum Tube
Note: This 7025 tube is now sold out. Unfortuantely we do not have an ETA for more. Consider the equally great Preferred Series 12AX7 we offer instead.
The Preferred Series 7025 preamp tube is a high quality 12AX7 vacuum 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. 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.

Preferred Series 7025 | Clear and Punchy
by Ryan Melvey
Swapped out some old Telefunkens in my Ampeg amp with these PS-7025 and my sound got more clarity and punchier. I play wurlitzer through the amp and my chords have a nice definition to them. The Telefunkens were probably pretty old so it's hard to compare, but I am happy I swapped in these guys.
Preferred Series 7025 | Need my ears to adjust, but very good.
by Doug -
I just put a set of these into an old HR Deville 212, and my initial impression was that they sound brighter. But that's not exactly right. What the PS-7025 are is crisper and more detailed than the GT's that were in there before. I'm now hearing more of the guitar's character coming through.
As a test I played and listened to Pink Floyd's Shine on You Crazy Diamond with a strat. And I found that the clarity of the recording was matched by the way the amp sounded now (clean channel, no pedals).
I'd become so used to the old, "blurry" sound of the GTs that this needs some adjustment to my ears. But I'm starting to like it.
Preferred Series 7025 | Not so good on 1979 Fender ProReverb.
by Bryan H. -
Too hot for a late 70s Fender ProReverb for my taste. Broke up crunchy around 5 on the channel, EQ was not as flexible. I ended up switching to JJ Golds. See review on those. I like my amp to stay clean on the channel all the way. The JJs did that the Preferred Series did not. Other may like that though.
Preferred Series 7025 | Great Tubes! Great Service!

Very nice tubes, great sound.
The full line of Preferred series 7025 tubes are great!
I will never order another tube from anywhere else, EVER!
The tube store can answer any question you have and point you in the right direction for the sound that you are looking for.
The customer service is fantastic!
Preferred Series 7025 | Too quiet for its own good
by J Ang
I was looking forward to listening to this PS-7025 tube on my vtl 7.5 preamp but it wasn't 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.
