The junkier stuff I've seen refers to some cheaper transistor radios from the 60s, clock radios, that sort of stuff. I have a few & they just don't strike me as anything special. I was cleaning out the shed where I have a late 40s Magnavox console radio & was surprised to see how empty the cabinet was, especially compared to the prewar Capehart I just lugged upstairs. No, its not junk, just not what I expected.
I like all old tvs and radios, don't get me wrong; for some reason Maggies have just never done much for me.
