A complete system for $225.00 isn't bad and it sounds like it was well taken care of. There are probably better prices but you don't know what you are getting. Plus you have the manual so you know how much power etc.

The receiver is Quad, I wonder if the turntable is? If so, you could hunt some old quad records off Ebay and have some fun. I did have a Blue Oyster Cult, quad, I'll have to check to see if I didn't do something with it like trade it off.
