68. Marantz 2230B AM/FM Stereo Receiver from 1976

Only 30 watts per channel, but more than enough for a bedroom system. Not a whole lot of info out there on this one. There's tons on the 2230, but not the 2230b. The 2230 has pre out/power in, the 2230b does not. That's sad. Anyway, I replaced the old lamps with some blue LEDs and it's a looker! Here's a picture of mine:
 

67. Acoustic Research AR XB1 Turntable from 1972

The AR XA had a real wood skirt, whereas the XB had vinyl veneer that looked like wood.
They are essentially the same turntable. The XB does have an arm lifter though and there are style differences, but they are basically the same. Nice and simple. In 1972 they sold for about $90, which is roughly $540 today. Here's one that I fixed up and sold to a friend:

66. Harman Kardon 930 AM/FM Stereo Receiver from 1972

With 2 Phono, 2 Aux and 2 Tape inputs, the 930 gives the user lots of options! Only 48 watts per channel, but that's more than enough for most people. It was priced at $480, which in 2018 is almost $2800. I bought it from a nice couple and gave it a good cleaning. If you decide to go after one, do know that the green dial only stays on white you have it in tuner mode. If you switch it to Phono, the pretty green display goes away. Here's a picture of the one I briefly owned.
