Thanks for the great suggestions. It looks like both
receivers are no longer available as new so it's back to the
drawing board. I would only be interested in the used market if
I knew the history of the receiver. I already have a good used
HF receiver. There is no big hurry as long as this one still
basically works. I just know the time is near when one will
spend more time trouble-shooting than using and that's the time
to consider a replacement.
