Description

New Plate Current Matched Quad of Genalex Gold Lion KT88 (6550) Vacuum Tubes

These are as close to the original Genalex KT88s as you could possibly get. Made in Russia, they look identical to the originals down to the plate structure. They even have gold plated grids, carbonized screen grids, and tri-alloy plates. It’s hard to get any higher quality in any tube than what the Genalex KT88 has to offer. If you’re looking for that authentically vintage sound even in your new production tubes, this is what you are after.

Will work in place of: KT88, 6550, 6550A

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.

    Probably the best KT88 tubes out there

    Posted by Jon Shimamoto on 9th Feb 2024

    I have tried the Psvane KT-88-T MK II in my Willsenton R8 and it is superior to the supplied Willsenton KT88 tubes. The Gold Lion is a better sounding tube, more musical and with better imaging and bass than both tubes. The prices on these tubes has gone up since the Ukraine-Russo war and is occasionally out of stock. But if it is available, this is the one to get. On a side note, while I like this KT88, I am somewhat partial to the EL34 tube. It is warmer sounding with a smoother top end but the KT88 has tighter bass and a "hotter" treble.

    They sound awesome!

    Posted by Elliott on 14th Feb 2022

    Installed on a Yaqin 100b amp that came with Psvane kt88 Gold Lion kt-88: Wide stage, very clear, plenty of power they just made all my music sound better, the vocals sound so good, I can now hear details I didn't hear before. I just hope I can at least get two years out of them.... If so I will purchase again for sure.

    Genalex Gold lion KT88 MC60 Amp

    Posted by Michael Anthony on 29th Jul 2021

    These are the best new production tubes I have tried in my Mcintosh MC60 amps. I put these in to use in order to save life on my new old stock original USA made Tungsol 6550s. Iam happy to say They sound almost as good as the 1960s Tungsols for a reasonable price! This tube is a winner and so is VivaTubes. Ultra fast shipping and the best prices too!
