What do you think a fair price would
be for a fully functional 77A with a new cable and the original desk
stand?

I don't know about 'fair' but eBay is useful for calibrating current
market value. If you do an advanced search for "RCA 77" and check the
'completed items' box, you'll see matching auctions that completed in
the last month or so. Note that 'completed' doesn't mean 'sold' (might
be no bid, or reserve not met). I just did so and found the following
that actually sold in June:

A dropped/dented 77DX for $761
A 77DX in seemingly good shape with case/cable for $1527
Another 77DX in seemingly good shape with case/cable for $1326
A banged-up 77D for $655

Sorry, no As, but I suspect that they would run a little less than the
DX, even though they are rarer. DX seems to be the most sought-after
model for reasons discussed in other posts in this thread. I've seen
mint (or expertly refurbished) DXs go for $2k, $3K, and higher.
