Does anybody have any idea? I own two of these receivers New Old
Stock, never used. These days they are good for almost nothing.
The R-278B/GR is a heavy tube type receiver that was used in military
air traffic control towers. Beside its today's uselessness, in my
opinion it equals R-390A in quality and workmanship.

I saw it once, it is indeed an incredible machine
