Comments about Mullard 12AX7 Preamp Tube:
I USE THEM ALL THE TIME GREAT JOB
Comments about Mullard 12AX7 Preamp Tube:
I bought these tubes to cleanup my stock Bugera V22 guitar amps sound and did they ever! If you're looking to get those bell like tones when you pluck those strings these will really help! The clarity is just spectacular, IMO.
Comments about Mullard 12AX7 Preamp Tube:
Ive been running Old, original Phillips type 12AX7's in my DSL50 for years. i have a nice stash and ive always looked down on the new 12AX7 tubes as junk. Out of curiosity i bought 3 of these Mullards and Im VERY happy with the sound im getting. In my experience the problem with new manufactured preamp tubes is that, even if they have a decent tone, they are limited in range and detail. NOT SO WITH THESE MULARD RI. im getting a very full range with the pronounced, biting midrange i love in the originals. the note definition is almost as good as the dutch amperex. Im going to buy some more of these, plus some Tungsols and some JJ ECC803's and give the new tubes a closer listen.
Comments about Mullard 12AX7 Preamp Tube:
curently running a vintage tb raxx(peavey)with 2 12ax7. it had sovtech wa's in it, decent sounding at best. tryed these and the tone noticeably inproved. very clean, musical sound. then i turn up the gain and the overdrive was impresive. i dont use distorsion much but the clean is very sweet. i would rate these as a mediem gain for you guitar guys, was considering tung sol but for bass i didnt think i needed high gain, glad i went with these!
Comments about Mullard 12AX7 Preamp Tube:
I have to agree with the guy who said its a waste of time and also misleading to compare these to the Phillips made Mullards of the 50's and 60's; NOTHING ever made is as good as those tubes were. That said, this Mullard from New Sensor is a pretty good tube. Somewhat mild in the gain department,(but not too mild) very clear overall presence. I do hear just a bit of the sound of an original phillips Amperex in these when they are over driven - good detail with a bit of the crunchiness and bite of those awesome 12ax7's. To clear up the "rebranding" confusion, these ARE NOT "rebranded" tubes. These tubes are NOT sold under any other brand name.They are made by New Sensor (an American Company) in Russia. New Sensor Owns the Mullard, Tung - Sol, Electroharmonix, Svetlana and Sovtek brands, just as Royal Phillips once owned Amperex, Mullard, Valvo and several other brand names. In my opinion and based on my trial and error experience, This is one of the better sounding 12AX7 tubes currently being made. I think it's probably best suited to Hi-Fi systems but i like them and use in them in My guitar amps. To me, they sound best in Fender and VOX amps, where a very clear clean tone with a bright high end is wanted. They sound good in Amps driving EL84 power tubes.
Comments about Mullard 12AX7 Preamp Tube:
So I got this as a replacement for the OEM 12ax7 in my 5 watt class A amp-the amp has only one preamp tube so its tone has a signifigant effect on the overall sound. This Mullard tube is a long plate design which many feel has a warmer tone while being potentially subject to more hum and microphonics. After nearly a month with this tube I am not happy with its tone. It is fairly sterile and low gain-which is frankly my biggest problem with newer tubes. However in this regard it sounds no worse than most current production tubes. My biggest issue with this Mullard is its buzz. This tube appears to have NO shielding. You cant tell everything by looking at a tubes construction but the buzz is quite clear even at lower gain settings. I tried it in another amp and even a preamp and the buzz remains. The one good thing about this experience, however is that I have been "inspired" to purchase only vintage/NOS tubes. I found a bunch of pulled Sylvanias, RCA's, and GE's for a song and have been having a blast-its a huge improvment. In general they sound better, have NO noise, and signifigantly more gain-and longer life. I have found a few that sound wonderful in pretty much any amp I put them in-and even NOS tubes are not much more than the 20 bucks this tube went for.This is not your pops Mullard. Its simply a rebranded, over priced, poor sounding tube.
Comments about Mullard 12AX7 Preamp Tube:
This tube Has a nice clear soundstage and good Overdrive crunch but not its really super high gain like the JJ's or the Tung Sol. I rated this tube against all other NEW production, not against Blackburn England Yellow Labels, or West German Telefunkens, as some people obviously do. No these Russian made "Mullards" arent up to the Old standard, but Ive comapared it head to head against the Chinese 7025 "Mullard copy" , supposedly I63 type, and this Long plate from New Sensor is superior in every way. This Mullard RI captures a bit of the orginals Detail and smooth overdrive whereas the Chinese 7025 sounds exactly ( to my ears) like the 12AX7A. A lot of drive and not much else. I recommend this tube.
Comments about Mullard 12AX7 Preamp Tube:
Ive used these tubes in various amps, in all preamp stages and im definately impressed. In The V1 position in my Marshalls they behave very much like an original Amperex. They have a somewhat "flat" sound, not much coloration,with a lot of detail and power just like the original. In the V2 position Overdrive distortion is definately smoother and easier to listen to than most new production, and a lot of old prodcution as well. Very pronounced highs, and high mids. Cuts right through with great detail but still lots of saturation. In an amps that are naturally bright these might be a bit too trebly; again just like the original Amperex. This has beome of of my three favorite New prodcution tubes. The other two are the Tung-Sol 12AX7 and the JJ ECC803.
Comments about Mullard 12AX7 Preamp Tube:
I have one of these in my V1 slot of my Blues Jr. and it performs very well. The sound is very balanced with good lows and highs. I didn't like it in the phase inverter slot as it picked up some hum from the power tubes but I think it is due to the long plates and high output. I would compare this tube to the Tung-Sols as they both sound very good, much better than sovtek or Groove Tubes. It has worked well without any ticks or noise.
