Product Description
Mullard EL-34 - A modern re-creation of the classic Mullard. Produced in Russia by New Sensor. We've been playing these in everything from the PrimaLuna amps to the Manley Classic 250s, and they sound great. Nice warmth, plenty of detail, but will retain a little more top end extension than the SED Winged C
Pricing above includes matching in any quantity you need at no extra charge.
All power tubes are Platinum Screened & Tested to the highest standards, including a 72-hour burn in process, and testing at real-world voltages.

Excellent
Posted by J Romanello
After careful consideration, I purchased the Mullard EL34 re-issue, cryo treated, for my Music Reference RM9 MKII power amplifier. After a short 6 hour burn in, I decided it was time for critical listening. After 25 hours of additional play time, I'm convinced that this is the correct tube for my amplifier. The sound is beatifully balanced. Bass is powerful and tight. Midrange is warm, clear and a bit forward. Treble is clean and extended, although, in my system, it may be a tiny bit more laid back than I'm accustomed to with 6550's.. but I've learned that I can change the treble perspective by swapping type 2 and type 3 preamp tubes... I haven't yet decided which to lock in. Overall, for my system, my taste in music and my ears, the EL34 is the best choice in a power tube and the Mullard re-issue is my first choice. I'll likely order a spare set. Thank you Kevin, and staff, for your help!

Suprisingly Good
Posted by Unknown
Kevin suggested these for my Quicksilver Mid Monos and they have not disappointed. In fact, I am quite surprised at how good they are. They have a confident, powerful sound, with balanced response top to bottom. I don't think they have any particular sonic signature - they just let the music through. Highly recommended...

Replaces xf4
Posted by Solerso
These are excellent tubes. Made well, with good quality material. This generation of power tubes being produced by the American co. New Sensor at the Reflector plant in Saratov Russia, are nearly as good, or even AS good, as the last years of production of Sylvania and Phillips branded tubes made in the US the 80's. They seem to be moving toward picking up the mantle of the old technology rather than just cranking out old Russian millitary types, which can only be a good thing. This Mullard reissue is powerful and has great balance. Low end response is not flabby. Midrange is Forward like most of the Phillips varieties.Nice heavy glass and the support posts are thick, and the getter is a normal "o" type, not one of those weird ,Russian, upside down flying saucers, which look to me like noise problems waiting to happen.The New sensor "Mullard" - EL34 and "Tungsol" - 5881 are without question the best sounding modern production output tubes, if you have something in the 50-100 watt range.

This tube works great in combination with the Telefunken ECC801S I recently installed.in my AudioPrism Debut Mk. 1. Amazing detail & 3D presentation while sounding warm and more powerful than the Winged C SED''s in this same combination. They do sound great, and they rock!. The SED''s had a more delicate sound and seemed to have a slightly recessed midrange, and seemed to lack he detail of the Mullards.
CRYOGENICALLY TREATED VACUUM TUBES. DONE TO UPSCALE AUDIO STANDARDS!
Most of you already know that Upscale Audio is the premier destination for expertise and availability of vacuum tubes for high-end audio equipment. So when we offer servies and options, you can be guaranteed that it represents a significant investment of research and capital, and that the end result will greatly enhance your listening experience.
Upscale has contracted with the foremost company involved in this technology, 300 Below, to treat our most popular tubes. Other tubes will be added as time allows, but it is a time consuming proccess. Our intention is to have most stocks Cryogenically treated before we even test them.
Of course, your first question is – and should be – why? In a nutshell, reducing an object’s temperature to -300ºF re-arranges its molecular structure, creating greater uniformity that results in longer life and better performance than when the product was initially designed.With vacuum tubes, this process has a profound impact on a tube’s ability to endure thermal shock. Therefore, tubes can last longer and their sound can been enhanced in ways that are simply exquisite.
After thoughtful and thorough research, Upscale Audio chose 300 Below because of their extensive experience in working with musical instruments as well as auto racing, metal tooling, and high-end sporting goods from rifle barrels to golf clubs. Expect nothing but the best from Upscale Audio.
Our charge for Cryogenically treating tubes is a fraction of what others charge, though we use the premier company. Count on Upscale to do the best job and not price gouge . Also available is cryogenic treatment for cables, along with our well-known Nordost Vidar cable treatment system. Call for details. Pricing is listed on each tube and cable page.
