Thanks to the ersatz “General” at RCA, a fair number of people in the U.S. were left with expensive pre-war consoles which no longer received FM stations following WWII. Some manufacturers made converters for their pre-war radios (Scott Radio Labs and Zenith come to mind), but apparently few people opted for them. Pilot and Meissner and probably other manufacturers made small table model FM tuners especially for these consoles and for the beginnings of the hi-fi market. I have examples of both Pilot and Meissner tuners. The Meissners are marginally better than the Pilots, IMHO, but neither are particularly sensitive. Both need all the antennae they can get.
