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!

@dinov  I bought them from Brent Jesse.  Do you know of a better deal on those tubes?
