Genalex GL KT88 Reissue on Conrad Johnson 12

This is second hand information, but I've read that about a year ago there was a bad run of GL KT88s and no real issues since.

And the handful of people I know who have tried the reissues has found them to be their favorites of all available KT88s. Some even more so than the originals. FWIW...

I am running these in VAC Avatar Super, I had an inital problem that was unrelated to the tube itself. They have been great since. They are absolutely fantastic sounding tubes.

I am running these on Audiopax Model 88 and find them to be excellent and a noticeable improvement from the Svetlanas that I was previously running.

Hello, I have never herd the original Genalex KT88’s before, but all I have read indicates that they were quite the tube and if you can find them know and do not need a whole lot of them they are still one of the best HT88 tubes out.

I am running Audio Valve Challenger Mono Blocks which are auto biasing and can use EL34’s, 6550 or KT88’s. The wattage also changes with the type of output tube; the real negative side of this is that each amp takes (6) SIX tubes! When you are buying Genalex Gold Loin KT88’s x 6 matched prs that is $550 BUCKS- well call me stupid but I dropped it for 12 bad boys and it was well worth it.

My amps came with Electro-Harmonix EL34’s and putting these bad boys in was a huge improvement, starting with just plan more power and with power comes more AC needed to keep the room cool and believe you me it sure gets hotter now; then a much bigger sound stage more controlled deeper bass. The EL34’s have a real luscious mid sound but the KT88’s really rock, especially with Swing Jazz (Big Bad Voodoo Daddy) and Blues (Buddy Guy). Well worth the investment for me, however now I got curious and went and picked up 12 Ruby Tubes (6550’s) and they are sounding pretty sweet (and over $250 less!)
