Probably better AM sections anyway (though a 1972-vintage Sherwood I have 
has an absolutely wretched AM tuner).  I doubt they have the FM selectivity 
of today's units.

At the very least if something goes wrong, it would be possible to repair 
(presuming you can find someone who can/will do the job) since they were 
all discrete components in those days (even if an exact replacement 
transistor was not available, a "close enough" replacement could probably 
be found).  That is a problem with today's equipment with proprietary 
"radio on a chip" circuitry.  OTOH, they're cheaper to replace than repair 
nowaday (though a bit disconcerting to my deeply ingrained Yankee frugality).
