Yes, the russkies kept vacuum tube technology in service long after the West had gone over to solid state technology.

The article doesn't mention Eimac , this San Francisco company was founded by two hams in the 1930s, it is now only a shadow of its former glory days, but is still filling a small niche market, making tubes for US military radar systems and radio broadcasting. The local ABC FM transmitter here on Mt. Tassie has Eimac tubes fitted !
