Does anyone have experience to relate with the reissued Telefunken Black Diamond tubes?


I am specifically interested in their EL34s as Tube Depot has a sale going on ($54 ea) and my current set of one dozen reissued Tungsols may be getting into that phase of their life that having another set on hand might not be a bad idea.

What I did find by doing a google is that they are "made in partnership with JJ" and are manufactured in Slovakia.

@immatthewj I got that email from them today also ,tempting.I like the J&J KT88,s I purchased from them nice robust sound but Id like to go back to EL34,s for a change I might go for it also.

They are spectacular. I have them in one of my systems and love them.

No tube is going to make Bruce sound good though.

@bikeboy52 , I sort of remember reading here that Tube Depot’s matching might be questionable.   And they do say in their email that they sell in matched quads, so I guess if I want a couple of sextets I’ll have to call them.  I also went to Viva’s sites to look at some EL34s, and those new stock telefunkens would cost  more there.  I wonder what the "UK Psvane  Hi Fi" El34s would be like?
