Description

New Plate Current Matched Quad of Genalex KT77 Reissue Vacuum Tubes

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.

    Genalex KT77 reissue

    Posted by Dave Harvey on 16th Feb 2022

    I needed a new EL34-style tube since my faves, the Winged C's, are almost impossible to find now. The Genalexes are the only KT77 I've tried, but they're wonderful. While I do miss the harmonic complexity of the Winged C's , these tubes are more dynamic – less compression, more headroom – making for an especially defined chunk when muffling the strings. I'm playing a 1970 Orange/Matamp, and they bring out the amp's throaty midrange better than any other tube I've tried in there.

    Fabulous tube! It takes everything you like and makes it bigger and better. Very quiet. More dynamic. Incredible soundstage. More articulate bass. I can’t think of a weakness. I held off buying due to the cost but these are a bargain. I can’t recommend highly enough. Great service from Viva Tubes made this just a great transaction.

    this is a near perfect tube. detailed, dynamic and not crazy expensive. I use in my PrimaLuna Dialogue integrated amp.
