Ratings & Reviews
I had a tube amp that needed a decrease to the output so I replaced the 12ax7 with this one and got magic superb mellow sound.
Thanks for this recommendation Tubestore!

Have had this tube installed in position V3 (Phase Inverter) in two HRDs for approx 10 years (both amps operate frequently each week). Have not had any tube last this long. The Mullard 12AT7 produces absolutely sweeeeet tone as it drives the output tubes.
by C. Monaghan
This is the perfect tube for the PI slot in a vintage era Hiwatt amp, really smoothed the tone out.
V1 in Effectrode Tube-Vibe Pedal
by Tony V.
Excellent service & product, as usual. I just paid a handsome price for my new Effectrode Tube-Vibe all tube pedal and it came with some mediocre JJ tubes, so I opted for the full Monty and got this Mullard 12AT7WA tube for the V1 position; I have some other NOS Mullard 12AU7's in V2 and V3. Wow - what a gorgeous, rich, deep & full sound! Awesome. Thanks, TS.
I kinda hate to write these up, but now that the prices have gone steep I don't mind telling folks these are the best sounding tubes you can find next to actual Mullard12AX7s. Aside from a bit less gain, they have all the warmth and complexity of their impossible-to-find counterparts. And if you want AFL the fashion, you still have the house-brand 7025 Preferred Series, which are awesome for a modern 12AX7 tube.
