[R-390] Dead 6MHz and 10MHz

[Fraser Bonnett]

Fortunately, some years ago, someone on this list sold a very long Philips
screwdriver and a wrench that fits on the back panel.  I was able to use the
screwdriver through two access holes in the back panel, to remove the cover
of the crystal oven.

I removed each crystal, cleaned the pins, and put Deoxit on them.  I
inserted each one back into it's slot, fired her up, and those previously
dead bands are working again.

Phew!  Thanks everyone for the pointers!
