1976, it was a battle royale with Pioneer and Superscope (Marantz), check out these new beauties from Pioneer. I don't know when Centrex came about but these are some of the better creamy crops from Pioneer, maybe that's why they weren't Centrex?
Sanyo MCD950F from 1989 HiFi Choice Magazine, is this the "Ultimate Boombox" Disregard the first two paragraphs.
Centrex by pioneer RK-356 Back Front Centrex by pioneer rk-114 also, My first ever boombox purchased in 1978 and there's a picture of me in my army clothes at work sitting next to my boss. It's on the internet somewhere. Back Front Centrex by pioneer RK-888. Back Front Okay and then All three Trying overhead picture The big one still needs to be repaired. I just haven't gotten to it yet. The middle one works fine and the first one I can't remember.
Yes, I like those alot, they come up for sale here about once a year but they aren't cheap. It was definately a Sharp Statement Piece for 1988.
