I have some stuff from the early 70's. It is the Nakamichi wedge series. (not the real name). It has a pre amp, tuner, power amp, cassette deck, a power center and a rack that holds them one above the other. I got it from a buddy who bought it new. I gave it to a young guy that I know and now he has no room for it (two new kids). So I am getting it back. Googled it and a set like this sells for about a grand! Woo Hoo!!
