[R-390] Re: [R-390A] BFO Question

Thanks to all who replied with your bfo comments.  A drop of oil on the
"unused" shaft smoothed things out a bit.  It still was much tighter
turning than the bad one in the radio or other good units that some people
had as could not be turned by my fingers on the shaft.  I believe this is
caused by an internal (o-ring?) seal on the shaft, similar to the one used
to seal the bfo(pto) case.  After many years of use this wears down
allowing the shaft to turn much easier.  It would seem that, this being the
case, the new bfo did not have a problem after all and turns as it should.
Perhaps this experience will benefit others in the future.

My Bristol wrench set came in yesterday, I installed the new bfo last night
and all is well.  It turns out that the internal core was broken on the bad
one.  I am almost brave enough now to drop the front panel and repair the
stuck microswitch on the function control!

BTW Am I allowed to listen to anything other than AM on this fine old radio
without getting flamed?
