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.

Fantastic 12BZ7 Replacement


I was very reluctant to try 12AX7's in my Cary Rocket 88R, but good 12BZ7 tubes are extremely hard to find. Jon recommended the Gold Lion (Premium) ECC83/B759 tube.

Now, I would never go back to the 12BZ7's. All the audiophile superlatives are so obviously present that I stopped analyzing and started enjoying music. These are a bargain.

I also bought Tung-Sol KT120 tubes and Tungsol EL84 tubes with great results but the Gold Lion's made it all gel.

Thanks Jon and Richard.

A phono stage dream come true


I recently purchased a Gold Lion ECC83 Premium tube for my phono pre-amp stage. This is an absolute gem for this application.

It is not as forward as some of the other modern reissues perhaps, but is controlled and balanced across the spectrum and has no hint of the "edginess" most others do. Warm blooming mids, beautifully delicate top end, and a strong but tight bottom. The level of detail was astounding. The sound stage is immense and immersive. Imaging is excellent. Complex passages are handled with grace and ease - it never sounds busy or overwhealmed.

Simply a beautiful piece of glass.

Killer tone


I have a Orange TH 30 and Marshall Vintage modern. I use this tube in both. Both these amps came alive. I have that tail end spark on notes that adds a really cool vibe. Think Billy Gibbons. They are constructed very well and the tone "KILLER"

Not worth it


This cost 3x as much as my CD player's stock EH tubes--and they sounded about half as good. They are certainly not kind to the human voice! (That said, they may work great for guitar amps, but that's not what I bought them for.)

All I can say is that the main benefit of these Gold Lion gold-pin tubes has been to make me appreciate just how clean, detailed, and neutral the stock EH tubes sound by comparison.

What the Five Star Guys Said


Totally smoothed out my brittle, overly bright Vox NT50H. Buy this and put it in your V1 and your playing around trying out different $10 - $20 12AX7s days are over. Defiantly worth the price.
