From our review - "Blues guys will go crazy for the reissue Mullard EL84 tube. It has the least clean headroom and can be pushed into distortion with aggressive playing. When pushed into distortion the Mullard EL84 tube has a softer, creamier overdrive that is more musical than other EL84 tubes and is the tube to pick if you want dirt."
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
If these are the 6BQ5, I have only one thing to say:

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.

Classic Rock Sound
I installed a pair of Mullard EL84's in my Marshall 1974x. The rich, creamy overdrive nails the early classic rock sound. Great tone!

Great for the TubeMeister18
I replaced the stock tubes in my TubeMeister 18 with a pair of these Mullard EL84 (and some EH 12AX7 for the preamp) and the already good-sounding TM18 now sounds fantastic. Rich but smooth texture. Easy to get saxophone-like sounds from the lower registers of the guitar, which is a sound I've been seeking for years. I use my TM18 as a signal processor only and can't vouch for these performing as well when driving a speaker - but they probably do.

Purchased a Fender Blues JR III and played it for awhile with the stock tubes which Fender claims to be GrooveTubes. A nice sounding amp right out of the box but I knew I had to modify it. I customize about everything I own! First was installation of "Complete" mod kit from Fromell Electronics", then re-tube, and lastly swapped out the Eminence speaker with a Celestion Alnico Blue. When I pulled the stock output tubes I noticed that contrary to Fender's claim about the attention paid to carefully matching their tubes and being number and color coded, they had installed at the factory 1 GT and 1 JJ. Only the GT had been number coded and no color code on either tube! Thanks Fender. Replaced these with a matched set of Mullards from TTS. When I first fired up the amp there was only a slight improvement of tones but an alnico blue requires 20-30 playing hours to break in and tubes need about 10-20 hours. After about a week this amp was producing sounds that I thought only came from $3000.00+ boutique amps. I used to really love the sounds that came out of my Kustom Coupe '72 but now I don't even use the Kustom anymore! Also, learned a lot about tubes from TTS website. Fast shipping from TTS. Also recieved phone call asking questions about matching triodes on the pre-amp tubes (JJ Golds). Great company.

mullard el 84
they're bigger than the original marshall el84's. have to modify carrier surround or housing in order to even install. hope they're worth it. why bigger?
Response from thetubestore.com: As stated in the product desciption above, yes, these tubes are made with a slightly wider diameter bottle. Why? We do not know.

Warm Dr Z Maz 18 NR
I purchased a matched pair of these Mullard EL84's for my Maz 18 NR. Instant warmth and creamy smooth break-up. Definite improvement (IMO) over the stock JJ's that were in it when purchased. Perfect match with my humbucker guitar

So I purchased a matched pair of these for my Orange OR15 head as part of the recommended "premium tube package" here at the tube store and I absolutely love them. In most cases I think people think they hear a bigger difference with tube swaps when they really that much don't but in the case of this tiny orange, I heard a vast improvement in the creaminess of the overdrive and the taming of the harsher high register notes. These are more than a solid choice for that classic British rock flavor in my orange amps. I haven't tried these in any other amps but in my orange or15 they are there to stay! Highly recommended and the price is extremely on point for top notch quality!

I have a pair of these in my Hughes & Kettner Tubemeister 18 and the amp really sounds amazing now. It came with Sovtek's in it and they sounded good, but replacing them with these was a solid improvement.

Total Sound Update
Put these in my Laney Lionheart L20H, Just opened the amp right up. Harmonically the highs and lows sounded excellent with much better definition and control, also spent time matching my amp with the right set of speakers.Great service, and shipping from the guys here at the Tube Store- Thank You !

Warm and Clear
I designed a four-EL84 tube amp for blues and worship music. I decided to try the Mullards. The amp sounds clear and warm, and when you crank it up, the natural distortion is very nice. My music teacher gave it a rave review. I bought a second set, and I'm building another amp with them.
I put a matched set of 2 Mullard EL84s (rated at 47) in my Orange Dark Terror a month or so ago and they are very stable with a nice even tone. They are also very warm sounding with nice breakup when pushed. Great tubes!

I have a couple sets of NOS for my Vox AC30 CC, GZ34 rectifier tube. One is Raytheon the other RFT. I haven't used either yet, because these new production Mullard EL84 tubes sound fantastic!!! I've picked another set up for an extra backup. Amazing long lasting tubes!

Very happy with the Mullard EL34
I've been using orignal Mullard pre-amp tubes in my Fenders for years. Thought I would try these new Mullard spec EL84's for my Peavey Classic 20. Good decision! It moved a harsh scratchy overdriving amp with a few sweet spots into the creamy side of life, with a wide range of usable sweetness now. Yields sweet thick warm and tonally rich sustains, amazing with slide. P.S. Tubestore matching: superb!

These things rule
I have been told that all the Russian EL84 / 7189 tube types are either surplus 60's era Russian Military or newly manufactured designs - except for this one.This tube (so I've heard) is based on a civillian tube that was intended for TV, radio and other audio use, with some engineering reworking by New Sensor. Originally a Soviet copy of a "Western" (no doubt Phillips) EL84. Ive also been informed by a Russian acquaintance that most Russian people never cared for the 6p6s types and greatly preferred these noval base pentodes. As for sound? These are AWESOME. Great overdrive tubes, don't even waste time trying them in stereo or headphone amps -just pop it right into a guitar amp where it belongs. I don't own any of these right now but I've heard 2 original (1962) AC30 amps loaded with them and they sound better than the old Phillips types in those amps and I'm not exaggerating.

Very Musical and quiet
I have used many different tubes in my Peavey Delta Blues 1/15. These coupled with Tung-Sol 12AX7's, my favorite 12AX7, Give me the tone I have sought for years from this amp,
