The NOS Mullard 12AT7WA / CV4024 / M8162 vacuum tube is low noise and long lasting. This 12AT7 preamp tube is a very good choice for hifi preamps, driver stages, and guitar amp reverb circuits.

These Mullard 12AT7 vacuum tubes were made in the Mitcham, Great Britain factory, in the late 1970's.

The 12AT7 tube type is equivalent to the European ECC81 tube and can be used in any 12AT7 or ECC81 circuit.

Mullard 12AT7WA / CV4024 / M8162 | Fantastic Experience all around!!!


First: I am stunned at how fast the tubes arrived. I ordered on Monday around noon and they were at my door in Pennsylvania the next day by 4pm. And that was with regular shipping, not expedited! Second: The tubes were packed better than any other tube dealer out there. I have ordered from various, well known tube dealers, but none of them took the care to pack the tubes like these guys did. The pins were inserted into a plastic protective sleeve and then the tube itself was wrapped in a protective paper cushion surrounded by thin cardboard. The tube was then inserted into your standard tube box. Best packing job I've seen. Third: the tube itself looks great and it's a NOS Mullard so of course it sounds great! Full, warm sound with slightly rolled off highs. I needed something to take the shrill coming out of my speakers and this did a nice job for the cost. Because of all this, The TubeStore will now be my "go to" for all my tube needs!

Mullard 12AT7WA / CV4024 / M8162 | Excellent

This is an excellent tube, in a different league than Mullard MU-12AT7WA Reissue which is good. Works very well with Mullard cv4004/12AX7.

Awesome sauce


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.

V1 in Effectrode Tube-Vibe Pedal


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.

This is the perfect tube for the PI slot in a vintage era Hiwatt amp, really smoothed the tone out.
