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.

Ratings & Reviews
I have heard these tubes through a Vox 1x12 with custom weber. A Vox normally lacks presence but these tubes just sing. Even through a cheap Ibanez we had to borrow I could tell the tubes specifically have special properties. Very, very clean and harmonics that you don't find in tubes from other companies. I'm going to buy these for my matchless as they have the perfect tonal properties for it, I could tell instantly.

If these are the 6BQ5, I have only one thing to say:
Mesa Boogie .22+ Calber EL84 tube replacement
Ok, just impregnated my 80's Mesa with a matched pair of these tubes and currently awaiting that birth of great sound. Of course I'll have to wait about 20 hrs to hear the beautiful result I've read about. So far everything's is quiet, which is a great sign. This is a .22+ Head pulsing through a Mesa Thiele 12in 200 watt EVM, for me now using this for jazz is overkill. However in my days of R&B/ Funk, nothing could touch it, not even those, Fenders and Marshals across to my right...wonder why I was by myself with my flamethrowing 22 watts!
4.5 stars, until I hear that aural baby cry!
Bought one of these for my VoxAC4TV and was hoping for a stunning tone and unfortunately I did not get what I was hoping for. From what I’ve read these are the tubes of choice for this amplifier. I currently have a JJ and prefer that tone as being tighter and not mushy like the Mullard. Maybe I got it bad tube. I tried them back-and-forth but in the end went back to the JJ. I wanted it to sound good but it just wasn’t the one. Always in search of the ultimate home.
These won't fit Korg Marshall Factory Made AC15TB, AC15TBX or AC15TB2
by Frank in Roanoke
I have a Korg AC15TBX and an AC15TB2 (made in the UK at the Marshall factory, it is NOT MADE IN CHINA) and I tried the new reissue Mullards but the problem is: THEY WON'T FIT the cutout in the chassis. They are too fat at the base of the tube. The only way to make them fit is to ream the metal chassis hole to the size of a US Coin (a Quarter 25cent piece).
