Description

New Gain Matched Pair of Genalex Gold Lion 12AX7 / ECC83 / B759 Gold Pin Vacuum Tubes

These are so close to the originals we could hardly tell the difference in both appearance and sound. Of course, these are made in Russia and not England like the originals; but that seems to be about the only difference. They really got this one right down to the gold pins, long welded plates, and even the getter shape. These are identical to the originals as far as materials, build quality, design and tone. These are one of the finest new production 12AX7s on the market today and hold up to their vintage counterparts.

Will work in place of: B759, 12AX7, ECC83, 12AX7A, 7025, 12AX7WA, 12AX7WC, 12AX7WB, ECC803S, CV4004, CV492, 12AX7 Gold Pins

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Gold Lion 12AX7

    Posted by Jeff Christian on 16th Jul 2022

    I bought this matched pair to replace the stock tubes in my Pro-Ject phono preamp. This is my first time rolling tubes. There is nothing wrong with the stock tubes, they sound very good, just wanted to experiment. Wow! It was like having a veil lifted between me and the music. The biggest difference is the clarity. The bass is more articulate, the highs are silky smooth without being sibilant. Overall impression is these tubes delivered that holographic tube sound I was looking for. The tubes arrived in just two days, well packed in bubble wrap. Will definitely shop here again after I get a Freya. Buy with confidence. Excellent experience my first time out.
