Aug 3, 2018 Location: nowhere. The Mullard 12AX7 long plate square getter is the best I ever heard. Seller stated Telefunken 803s are not as good at $1K+ each. A tube I thought is better than the 3rd place Mullard 12AX7 round plate are the Raytheon 5751 windmill getter. All are black plates.
Jan 21, 2013 Black Plate triple Mica -military 5751 - same review as the non-military version however, this is a supreme quiet tube. In a console amp (Motorola, Maggie, etc. ) brings out the best of the best. Haven't found a need for the Mullard or Tele's in the consoles so these are the ones.
Oct 17, 2007 CV4004 - The Mullard CV4004 is rugged version of the 12AX7. Made for the English Military, the CV4004 is one of the best 12AX7 variants you can use for audio. 5751 - This version was usually the one made for the US military. These have a lower gain than the 12AX7, but are otherwise totally compatible.
A lot of people love to use these 5751 tubes in place of a 12AX7 in the first preamp tube position. They have a gain of 70 versus 100 in a 12AX7.This is a Mullard tube from the 1960s I believe. I think this is actually a NOS tube. Nevertheless it tests like new. What's a l...

Mar 11, 2016 Review JJ ECC803-S Tube. This JJ ECC803-S / 12AX7 vacuum tube offering has huge plates in its triode sections giving it a real punch with lots of gain.

Oct 13, 2007 Recieved the Mullard Re-issue yesterday, and installed it in my Bellari V129. I must say this is a wonderful sounding tube. After about 10 hours of burn in, and listening late in the evening here is my review: The Mullard 12ax7 reissue is being compared to a GrooveTubes 7025 with a bit more burn in time. (20-25 hrs).
Dec 5, 2015 The JAN 5751 is great for the PI slot and even V1 as well. So various combinations might look like this Mullard - JJ - whatever - 5751 Mullard - JJ - whatever - Sovtek LPS 5751 - JJ -...
Apr 11, 2011 In my Dynaco SCA-35's phono section, the original Telefunkens are still sounding great. I also tried some of the new Mullard reissues, and they are no slouch -- it's not like the Tele's are in a totally different league. The Mullards sound really good, and the bass is absolutely huge. I also have some RCA 7025s that I'd like to drop in at some ...
Jul 16, 2002 Mullard CV4004 (83-85). VERY nicely balanced and extended, similar to GE 5751 with great body. Less air than the best 5751, but better balanced than Tungsram or Raytheon 12AX7. Great in Alpha DAC, better than rest in my circuit, until I tired the Tungsram 12AX7. Amperex 12AX7 is also quite good--like the TS, but missing some clarity. Lively tube.
May 3, 2007 I use a matched set of 5751 NOS RCA from 1959 in my Belles 21A preamp. I went to them from Mullard 12AX7. I found no audible difference in gain with my system. I found the RCA's to provide a little more air and detail between instruments, a little more depth of soundstage and very nice extention and tightening of bass.
Apr 17, 2018 The best tube rolling advice I can give for the Oto is to get some 5751 tubes for the preamp section. It has kind of a hot preamp without much range in the volume control, and they tame it some with the stock Sovtek 12AX7WA which uses a lower gain then a standard 12AX7 but not quite as low as a 5751.

Mar 10, 2014 For hi-fi gear the Mullard will likely be a winner but there are better choices for guitar amps for less money. Posted in 12AX7, 7025 and 5751 Tubes.

Jan 1, 2016 It works with every musical genre. The sound quality is right up there with the Shuguang black bottles but this comes at half the price. This tube does it allhuge reserves of power and headroom, a massive airy soundstage but in this case airiness is not a sign of thinness or an unsaturated midrange.

Sep 25, 2015 4.5. Ideal in any amp. Summary: The Mullard 6L6GC tube's firm bass response and detailed sound make it ideal in any amp, including high gain combos. First off, I should state that Mullard never produced a 6L6GC. This is not a reissue, but a brand new tube. The closest Mullard made in England would be the KT66 and KT77.

Mar 1, 2015 4.5. Summary: This tube could be the antidote to brightness, edginess and leanness. One of the most famous brands in the history of vacuum tubes now belongs to a different entity.
