Hmmm. I seem to recall that the attraction of solid state record-
players and radios in the 1960s wasn't better performance but lower
per-unit cost than vacuum-tube systems.

	Mind you, my father was a vacuum-tube fan in the 60s (Switched
to solid-state in the mid-seventies and then abruptly died; no doubt
there's a lesson in that) and his account could have been biased.
