The general rule today is that you can either new tubes from China, or New Old Stock (NOS) leftover from product in the US, Russia, or elsewhere.

Brands don't matter much in this world.  At most, they reflect a warranty and pre-testing. AFAIK there are no new high-power vacuum tubes being made outside of China.
