Mine was a Pioneer under their Centrex (sp?) line I think made in 1978. It had a built in 8 track player, and the speaker outputs were RCA cables. Funny, I though it was pretty high end since it did not have a built in turntable (like many others at that competing price back then) so I used a seperate standalone BSR turntable and thought I was getting much superior sound since they were "seperates" to me. Hey, I was only 12 or 13.
