Since I won't hurt your feelings, I would have difficulty choosing anything to keep. But if you want to set up an entire vintage system, then the advice of Jaybo and Ausjoe makes sense.
I am intrigued by the Fisher, although I am not familiar with the particular model. Fisher and Marantz were two gentlemen who were venerable designers of a bygone era. Very old Fisher and Marantz gear could be very good for its time.
I had an old Fisher amp during my college days back in the 70's. Many happy memories occurred with that unit playing.
