Probably bad caps.
Yeah. But caps in transistor radios of that age lived
an easy life compared to those in tube radios, so
maybe could survive longer.

I don't know. I've had several KLH Model Eight table radios, all well over
40 years old, and none had electrolytic problems.

i dug an old macintosh 50w-2 tube amp (mono) out of a dumpster a
million years ago. it still worked, but almost all the caps were
crummy, electrolytic as well as oily paper, as well as several other
components. replaced them and it was a nice amp. when i sold it the
buyer was shocked that i would desecrate a classic amp like that. (i
had kept the removed components in a coffee can which went along with
the sale, so he was free to return it to its natural state). what made
it a mcintosh was the transformer(s?) which remained original, as they
were potted in about ten pounds of epoxy or something and made up 90%
of the mass and volume of the thing.
