I picked up a couple of these to replace the stock tubes in my Manley Jumbo Shrimp. I was not expecting such a night and day difference. The mids opened up into a silky smooth velvety sound that I didn’t think my equipment was capable of. The bass is deeper and more pronounced. It is almost like hearing my records for the first time again. If you have a Jumbo Shrimp, I can’t more highly recommend these. Truly incredible difference.

Bought these (CV4024) and asked specifically for some very quiet ones for my phono pre. What I received were pretty good, but not as quiet as the original tubes. I expected a bit better for the price. They do sound very good though, so I am happy enough.

I wanted to clean up the sound of a Marshall DSL 40C and use it to amplify the natural resonance of a hollow body guitar. The Mullard CV4024 in the first stage preamp position worked beautifully! Better than all the current production tubes I tried.

I use this tube in a Pangea hp-201 head phone amp/preamp. Not a 10000 doller unit but I tell with that tube it really sings. For the money cant beat it. Love it. Highly recommended.

Used it in an amp I built using the iron and glass from a single end Admiral console. I've been listening to the original 12at7 from that console and it was very nice. This new AT7 is a world of difference. It's more open, detailed, and a lot more fun to listen to. Glad I bought the tube!

Overall sonic signature is smooth and rich. It renders some of my brighter CDs more enjoyable. At least as good as my 1960s era Telefunken 12AT7, maybe a smidge better. Highly recommended.

I own an MP3 Preamplifier from Atmasphere. This preamp uses six 12AT7 in the Phono Stage and a 12AT7 as a Voltage regulator. The 12AT7's arrived as promised, on schedule. Once I replaced them, the improvement was immediately audible. The Phono Stage is now much more resolving and relaxed, I can listed at a higher volume and attain more depth instead of just gain. There is much more inner detail than the stock Chinese 12AT7 Tubes. The cartridge I use is a Denon DL-160 on a Linn LP12 w/ Origin Live Advanced and Akito II arm. Thanks Uncle Kev for another Home Run!
