[Milsurplus] Broken shafts (was BC-779 questions...reformatted..).

[W7QHO@aol.com]

The receivers under consideration here have, by now, spent a long time in 
rather rough environments, both during their military "careers" and later bumping 
around in warehouses, flea markets, basements, garages, etc.   A phenolic 
shaft just won't survive a hit like a metal one will which may be the reason so 
many turn up broken now days.   I've also run across several cases with 
BC-312/342 receivers where the phenolic shaft apparently swelled and seized 
up in the front panel bushing and I imagine these frequently got wrung off by 
heavy handed operators.   In regard to rough handling it's interesting to note 
that all the later 312/342s had stop pegs on the front panel to prevent the 
bandswitch from being forced beyond it limits and a slip clutch on the main 
tuning knob to protect the gears.   Earlier models didn't include these features.
