Open the Winradio, and marvel at the beautiful subminiature components
surface-mounted on both sides of several densely-packed multilayer
boards, meticulous craftsmanship, and not a single adjustable
component in sight.

Yes, most disposables are made that way.
Very astute observation. :-)


Anyone with any electronics experience would know that components have
tolerances. The variation between components will mean that a non adjustable
tuned circuit may very well not be tuned as well as it could be. Making
things non adjustable is cheaper but the trade off is that you have to
except less than optimum performance.
