Sitting in the basement is a Sony CRF-160 - a cheaper alternative to the
320. It's a huge, heavy, dual conversion analog multiband portable from
the 1970's which selects the shortwave bands using a revolving drum selector
and bandspreads each SWBC band.

Over the years I'd used it occasionally and, apart from crankiness of the
drum selector contacts (which usually cleared up when worked through a
few clicks back and forth) it functioned quite nicely. Very sensitive and
selective, with that superb bassy audio that older Grundig sets are also
known for.

Now, after a long time sitting unused, I find that both the AM and FM
flywheel tuning knobs are frozen solid and can't be turned. Assuming that
parts aren't available for something of this age ... but perhaps there is
something inside that can be lubed or rubber replaced ... I'm soliciting
opinions as to whether this is even worth trying to get repaired.

I don't have the time or inclination to do it myself ... how would one go
about finding a shop that specializes in restoration of this type of rig?
Or perhaps a collector that would like to add it to their collection
regardless of functional state? Any ideas?
