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.

Killer tube as a phase inverter


I've been tube rolling in the 4 amps I have (Blues Deluxe, Bugera V22, a modified Epi Blues Custom 30, & Vox Ad100Vt). I found these to be the Holy Grail in the P/I position. I've tried them in the first stage and the tone stack positions, but for my taste I prefer JJ ECC83s in the first stage and Tungsol 12AX7 tubes in the tone stack with the Gold Lion as a Phase Inverter. These will really wake up your amp. Extremely satisfied.

Used for maybe 6 months in my bass rig.....crapped out during gig....not worth the money,,,especially for 6 months

I want more of these tubes! The Gold Lion Premium sounds/feels ever-so-much-sweeter than a Preferred Series, Tungsol, Mullard, JJ (7025/12AX7/ECC83)...All of which were brand-new during comparison test. Currently have Tungsol 12AX7 in V2, Mullard CV4024 in V3, and Winged 'C' 6L6GCs Biased @ 68. Ordered three tubes on Monday, package arrived Thursday (from Canada, no less!). 'TheTubeStore' shipping is simply superb.

What I am hearing...


I bought a pair of the Gold Lion 12AX7 tubes to use in the preamp section of my Jolida 3502 integrated amp. I was using a pair of Philips 12AX7 tubes prior to the purchase of the Gold Lions. Based on all of the positive reviews I have read here, I took the plunge and bought a pair. After about 48 hours of burn in I decided to give these a critical listen. I was hoping that I was to discover some current production tubes that would give NOS tubes a run for their money. Alas, it was not to be. I found the Gold Lions (GL) tubes to be harsh, rather two dimensional, and not as involving as NOS tubes. Soundstaging has shrunk in width and depth, piano music sounds tinny and flat and my favorite female vocalists sound like they are singing with their sinuses clogged.

At this stage of my listening, I would have to warn others to save their money and get some NOS tubes if they value their hearing. BTW, I have owned tube gear for over 20 years and have been exposed to various brands of tube equipment as wells as dozens of brands of tubes so this is not a review from a neophyte. The point is that these tubes are not very good and certainly not worth what is being charged. These may be great in guitar amps as was previously mentioned, but not in a serious hi end piece of gear.
