Anyone use any of the new Telefunken USA tubes?
Any good?

My3gger said:Not long ago a few of us here were talking about using NOS tubes vs new production, i was asking about strange eBay "NOS" offers. Too many are fakes, or used too much, prices high for good ones, so very unreliable and expensive. Getting good sellers elswere at least in Europe gives similar problems. Diy or not, we came to conclusion new production is the way to go because sound is good. If tube is not made new, than NOS.

JJ tubes sound great but you will probably have to replace them more often than a NOS tube,
and their 6L6 tubes bias up at 46 volts instead of 52 for a plate voltage of 460, so they are kind of like half way between a 6L6 and EL34 bias wise.

In opposite to most people here I had many bad EH tubes, though, and find JJs to be a lot better (=less microphonic, more consistent). But lately I´ve been using TAD tubes. They use selected chinese tubes and have their own inhouse QC which is true and not only marketing blablabla. I´ve been there several times and seen it, as well as I had conversation with the owner about tubes etc. As you might think you get the better tubes when buying their selected premium line while you get the rest if you buy the cheaper ones...
gyraf said:The "value-adding" cryo process is audiophoolery imo. Only helps in the "legitimizing heavy cost" parameter.
Think of it: The process is simple enough and very-cheap to do on an industrial scale, yet none of the great tube manufacturers did or do this. :
