A customer comment: "I ordered two Gold Lion ECC83/B759 tubes a few days ago and I put one of them in the first preamp stage of my Rivera combo. Fantastic! On clean or distortion, both are absolutely fantastic! It provides good definition, fast attack, extended high frequency response, and full harmonic content. They are the best ECC83 / 12AX7 tube I've tried! And they are not overpriced rare NOS! - 10/10"

Original Genalex Gold Lion ECC83/B759/12AX7 tubes are considered among the best 12AX7 tube 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 / 12AX7 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

One other note about the construction of these tubes is they have filaments that are almost completely encased in the plate structure. They don't "light up" brightly when working properly.

My Review


You guys are awesome!
Got some Genalex Gold Lions ( ECC83/B759) for my McIntosh C2300. I don't know why McIntosh doesn't stock this wonderful amp with these tubes brand new!!

Solving a Problem


For the last few months I got a problem with playing some audiophile LPs. Pops, clicks, distortions. Not on all of them, only 5 or 6, even within one LP one song could be OK, another was impossible to listen to. I have EAR/Yoshino 834P Delux phonostage. Talked to the manufacturer, changed interconnects, put an additional ground. Useless. I suggested the problem was aging tubes. After talking to Tubestore three times I decided to buy Gold Lion 12AX7. Got them in two days and after warming them up I put the LP that gave me such a headache the most. First impression is all problems disappeared, the sound is free of noise, very quiet background, clear, deep and wide stage.
No complains. Good tubes. May be later I add some more information after listening more LPs.

Great Sound


I buy a 3 Genalex Gold Lion for my Chinese ys-audio preamplifier instead of the 4 old years factory Chinese. If at the beginning the preamp sound like heaven, now it sound like the nirvana.... My AL-III carver dipolar speakers sound better than ever, great tubes, and arrived to my city in Mexico in 20 days. I get the the best service from the tubestore guys.

Deep and Rich


I've been using the Gold Lions for a few years now, and they are just deep, rich and beautiful... bass galore and rich mids. They are not the most sturdy of 12ax7s out there, I had one in my onboard guitar tube-preamp and it didn't last super long, but I'm hard on guitars :) The gain side of my amp sounds glorious with them.... well done Genalex.

I'm about to put these in a bass drum tube DI box... I'm excited...

It's about Time


Finally a new production tube that is as good as old production. I purchased 10 JJ's from various sources. 8 I had to throw away. I thought my Eico 666 tester had gone bad. I put in my calibration tubes, all good. I tested about 40 tubes I have, Ei, New Mullards, JJ, Chinese, Ruby (Like I said Chinese) sovtek 7025, Ge Nothing tested higher than 103 and the only one side. That was the russian 7025 but only 1 out of 3! Then I tested the Gold Lion ECC83 tube. The pair I have both tested at 123 on both sides, perfectly matched and at NOS Telefunken gain levels. My favorite tube is the Raytheon black-plates. I always keep them in V-1 and V-2 on my 1972 Fender Quad Reverb. I have actually retired them and installed these. So far my amp sounds great. The Raytheons have seen a decade of hard use and are testing lower so it was time but the tone is to die for, very hard for me to do. I will update how the tone compares after some break in Jamming (a few weeks). So far extremely pleased. It's about damn time. I will stop wasting my money and buy these from now on. (although I am curious about the Northern Electric 12AX7)
