HAve you seen any of them? Lots of complaints about build quality,
and looking like they were made first thing Monday morning, after a

Electronics still supplies transmitting tubes. They bought Eimac, and
other high end US tube manufacturers as they were dying off. Would you
trust a Russian clone of a 4CX1500?
