I was wondering whether the set will work with a box because of the IF strip, not because of the tuner. If this is a late 1940s set, the video IF may be 28 MHz (which, BTW, is why so many of these early sets would pick up local amateur radio operators transmitting on ten meters) or some other oddball frequency, not 41 MHz as all sets are today. Aren't the converter boxes set by default to operate only with TVs having 41-MHz video IF strips? I don't see how a modern converter would work at all with any TV made before 1960.
