I have recently taken my receiver out of storage and took it thru a very
slow power-up using a variable transformer - watching very closely for
smoke. All went well and simply touching a short piece of wire to the
antenna brought in WWV at 10 mhz quite clearly. It had been in storage for
about 8 years - in a heated and air-conditioned environment.
I noticed, however, that the KHZ operated smoothly but made a sqeaking
sound. Past unpleasant experience with commonly found household lubricants
left a messy varnish-like residue which was very difficult to remove. Any
ideas on what might be a good lubricant? The cams are dry.
Also, the gears themselves had a white grease on them when my receiver was
initially obtained. Is there a special lubricant for this? Where can it
be obtained? Is there an alternative?
Thanks
My receiver: R-390A/URR made by Capehart SN: 1070 (mostly). It has been
thru the Depot Maintenance System so the set isn't "pure".
