Genalex Gold Lion ECC83/B759 (12AX7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC83/B759 tubes are considered among the best 12AX7 types ever made. They are hard to find and when they are available, they are expensive. They exhibit a large detailed soundstage that is sought after by discerning audiophiles who demand the highest quality sound. The reissue Genalex Gold Lion ECC83/B759 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

Product Reviews
I have been using these tubes in every amp I own. They seem to push the power tubes better than any other I have used (whatever came OEM). They also seem to make the amp sound fuller and richer and more robust as far as I can tell. They also appear to be very durable. I Run my amps with EVERY knob cranked up as far as will go (and then use an attenuator to control the volume). I haven't had one fail yet.
I was looking foward to trying this tube out in V1 of an amp (S/E el34 based, 3 preamp stage) that I just built/designed. Unfortunately, it was extremely microphonic and completely unusable in this position; V2 it was great, but I prefer a Mullard in this stage (CF). I'm NOT knocking this product, but in a high gain amp at V1 I'd steer clear. Later positions would be better....lots of gain, good freq. response, but WAY too senitive for my build. Also, guys, if you intend on putting it in a 'normal' plexi, or bassman design, i.e. 2 preamp stages, not 3) this thing might rock! I tend to agree with Blackplates rewiew of this tube...it might REALLY work for you, or REALLY bummed you out. I was bummed... but as I said, I believe it can work well, but in the right position, with the right amp design.

Id like to add one comment to my review...The noise problems these long plate gold lion tubes suffer from could probably be solved if New Sensor would manufacture them with the correct, "star" shaped mica spacers..the ones with the little saw-blade points all the way around them.Look at any/all of your old Mullard, or Telefunken 12AX7 tubes.They all have those kinds of spacers..theres a reason for that..Those spacers distribute the pressure evenly all around the inside of the glass tube and cut down on vibration..Gold lions 12AU7 uses the proper spacers, why cant they put them in the premium 12AX7?
A VERY good sounding tube in all the Marshall piggy-back guitar amp heads Ive used them in .Believe it or not, this tube competes with my (real, Blackburn) Mullard long-plate 12AX7 tubes for quality of tone, in those amps. It is the only modern ECC83 type ive found that I can make that claim about. That said, I do not like them in combo amps, because of noise/vibration problems. They do-not work well in my Fender amps, possibly also they don't like to hang upside down .I REALLY really wish new Sensor, or Tube amp doctor or Groove tubes, would put the time and cost into producing an authentic reproduction of EVEN ONE of the great 12AX7 tubes of the past.There are many to choose from..so maybe the Mullard long plate would be too costly..I dont know..But what about the little RCA 7025 ? Or the GE 12AX7 short plate ? How about the Tungsram 12AX7? I would gladly pay $40 or $50 each If someone could put those tubes back into production...
