The Mullard name and trademark have been acquired by the New Sensor Corporation. This new production Mullard EL84 tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia. New Sensor is an American corporation and since taking ownership of this factory has been steadily improving the quality of current production tubes.
Note: These tubes have a slightly larger diameter than other EL84 tubes so they can not be installed into some '90's era Marshall DSL201 or DSL401 amplifiers, some '90's era reissue Vox AC15 amps, and Bad Cat amps.

The Goldilocks Zone for a VOX NT15H Finally Achieved
by Frank Lee -
I've gone down the rabbit hole with a Vox NT15H (v1), checking out just about every tube, every speaker that's easily accessible, and I finally feel as though I have this amp dialed in. (Contrary to what many might say, no matter what tubes or speaker used, it is very much like an AC15; and in its bright mode, it does wonderfully Voxish clean chime and top-boost crunch. In its thick mode, it also does a pretty good crunchy tweed-like thing -- with the wrong speaker, wrong tubes, it only gets about 75-85% of the way there, though -- with the wrong stuff, you can also achieve ice-pick highs and honky, cocked-wah-like mids, so I understand the mixed views on this amp). But with these Mullard EL84s, Mullard CV4004s and an Alnico Blue or Weber Bluedog, I've finally found this amp's right stuff. She's finally in the proper Goldilocks zone. (For those curious, JJ's EL84s and 803S large-plate preamp valves were very close, coming in second place for me.)
