What a time warp! I was also in college in the 70s and it's downright scary how very similar my first set-up was to a lot of other posters:
Sherwood stereo receiver -- #1 rated in Consumer reports back then, as I recall
Pioneer Dual cassette deck -- don't remember why. I guess I wanted to make copies or something
DSR Belt-drive turntable with a strobe disc to precisely calibrate the speed
Teac 2300S real-to-real deck
AR-6 speakers -- the cabinets were unfinished, so I had fun staining them.
When I was assigned to the UK (USAF) in the mid-1980s, I bought 50Hz conversion kits for the Teac and turntable: larger spindles, different size belts, etc.
My first full-size TV was a 1979-vintage MGA with digital tuning. I still have it and it still works. It's hooked up to a converter box and is in front of our treadmill. At the same time, I bought one of the first Panasonic "top-loader" VCRs, because I wanted to tape the 1980 Lake Placid Olympics. I still have the tapes somewhere, including the entire set of hockey games. In 1979, the VCR cost ~$500 and each 2-hour VHS take cost ~$10.
I still have everything except for the VCR. I even replaced the woofers in the AR-6s several years ago.
