Sadly, I have a beautiful condition Technics turntable from that period. Cast Aluminum, made in Japan. However, I could not find a comparable receiver from that period at any reasonable price, with the expectation that it wouldn't require work, so it's hooked up to a modern receiver that's commodity on Amazon. The sound of this setup is pretty solid given that the vinyl is as old as the turntable, but like the receiver, the 3-ways are contemporary. I've replaced modern receivers at about 1 in 10 years going back to a Sony ES and my current Yamaha is about that old. I'm sure if I had the skills, it's just a power supply or amp or something similar.
