Has anyone tried the new Telefunken Black Diamond tubes?

I was surfing the web for KT88's and I saw there is a new production series of Telefunken tubes called Black Diamond. I think they are made by JJ.


The KT88's are pretty pricey at $84.99. They have preamp tubes as well.

Has anyone tried these?

I think you'd be better off with the Gold Lion KT88s, which are favorably reviewed and very robust. JJ power tubes make me very nervous . . .

They are JJ tubes.

The only difference: a supposed cryogenic treatment and a Telefunken logo that has no business on JJ tubes. (or rather, a Telefunken logo that JJ tubes have no business sporting)

With JJs rep for power tubes, I'd be very cautious.

The great names don't mean anything these days, they just got bought, that's all. A JJ is a JJ unless they resurrected the people and machinery.

I am, as some of you said, nervous, and cautious about this offering.

Not to mention that the price is higher then most other brands.

Regarding the Genelex KT88's I know folks love them but I had lots of issues with those so I have not put them back in my amp since. I had one of those tubes take out a resistor on the PCB, one that went pop, and another with a filament that went out, all after not being in my amp for more than a few weeks or months.

I was in a KT88 tube rolling mode, so I guess I will look for another brand until someone else tries these new Telefunken's before I do.

Thanks
