Ironically I think as much innovation and intelligance was required in the 
other camp: mad man Muntz and his cheap TV sets and Hallicrafters.  Those 
guys would build a design and remove parts until it no longer worked. 
Designing the cheapest possible radio out of discrete components that can be 
reliably mass produced is no mean feat either.

I absolutely detested trying to fix them.  I worked in industry on the
broadcast equivelent of the R390 where trouble shooting and repair were
pretty easy - I did not care for my occasional exposures to minimalist
consumer electronics.
