I just bought some Telefunken smooth plates for $260 a pair.  He’ll have to beat those numbers and sound quality.  At least until the NOS tubes totally dry up.

There was a link posted elsewhere that said they bought the actual Mullard Blackburn tooling for the 12AX7, so if accurate they should be identical to those. NOS tubes. I’ll post the link if I can find it again. 

Love to hear what these tubes sound like. @shawn3997 wow, you bought at the height end of the market on those!

We need Russian mil-spec 6H30DR. The most popular driver tube of the last 20 years? The NOS, from the 80s - 90s, are night-and-day better than other brands/designs.

Thanks for posting!  I saw the same article last night and read it with great interest.

Lets all hope his new business works out and is successful!
