EAT KT-88 tubes

Of course it was after 6 months. EAT/Music Hall replaced the first tube, but I haven't received a response on the second.

For the statistics: in 8 months (please don't ask me how many hours that is, though) no problem of any nature with the two I've been using. Keep my fingers crossed.

how much does a pair of these kt-88 tubes cost? where did you buy it? heard from review they can make your 2k amp sing like 20k amp.

In Germany EUR 450,- for a pair (matched, obviously).

Ignore those exact figures for a moment. I bought them for my EUR 2.2k Unison S2K, a very big leap of faith indeed. But one I have never remotely regretted from the first moment on. Can it compete with a 20k amp now? Don't know, but it sure has become another amp, definitely better in every respect (you're spot on:"sing" is indeed what it does).

I just received word from Mussc Hall that the second tube will be replace at no charge. I think the US retail is $800.00 for a matched pair. Expensive, but worth it.
