It will be interesting to see the comparisons between new and old and if the amplifier will be any good.
Is it really WE or just someone who purchased the rights to the name? Who has all the engineering drawings and documents?
It takes a lot of money to tool up to make tubes and a lot of expertise. There is nobody left from the original WE crowd that could do this anymore. What happened to all of the original tooling to stamp out all the intricate parts? Where will they be able to buy the original sheet metal with the special coatings and such arcane materials that were used in tube manufacturing? No steel company will even entertain quoting the material unless you were buying mass quantity's of it, ton's and ton's of it. Back in the hey day this was common material to source and special coatings were common. Today, there is very little need for it.
My guess is that IF they are built in the states, material and stampings will be sourced from China. Will they have the exact same property's as the originals? I think not. Either that or be prepared to spend many thousands of dollars per tube. Very high volume is the only thing that drives prices down. Tooling and bulk buy's of material can than be amortized over a lot of units. This is the reality of manufacturing. Whats the market? Maybe a few thousand a year if they are really good and not to expensive.
When I would quote a machined part, one part might be 500 bucks, 100 parts could be 25 bucks each or even a lot less. For one part I had to charge all the setup time, any special tools purchased and a high price for a small piece of material. Metal warehouses nick you pretty hard when they have to cut a piece off a bar. Sometimes it was cheaper to buy the whole bar!

I never troubled myself to look up the 91a/b 'til just recently. This sacred cow apparently uses pentode voltage amplifiers, tons of electrolytic caps, and negative feedback!

For the Merrimack Valley Western Electric plant mothballed tooling & materials were rolled into scrap metal dumpsters when the Lucent reorganization took place. And that was for stuff used to make gear far more recent. By that time, mid-90s, it's almost certain that anything remotely vacuum-tube production related had been repurposed into other assembly lines or scrapped long before. I'd bet that was the same for plants all across the country.
Again, rumor or lore
You know, I think he did buy gear out of the KC works but believe that was in the early 90s and not when 300Bs were last made there. IIRC that was a ~decade earlier.
I especially like the 'add to cart' button for the monoblocks at $50,999.00 pair...

Maybe I'll just add 4 to my cart, just for fun.![]()
