I won this Quad 8 deck on Yahoo Japan Auctions this morning with the kooky plans to incorporate it into my elecric assist tricycle. What I do not know is if I am going to need a quad radio as well, or maybe a power amplifier. There seems to be no info online for this model. I do not even know if it works yet. For 1000 yen plus shipping, I was willing to take a chance. Looking at what wiring I see, it almost appears as if I need to hook up the antenna to the quad 8 deck and the front channels to the radio and the rears to a power amp or directly to speakers. I was kinda hoping for an all in one unit for simplicity. Does anyone out there have any info on this model or wiring info? If I need a radio as well, will any model work or at least maybe one with cassette if I need to go that route? Kooky I know, but if I were normal, er, I better not finish that thought. Also, if I need parts, especially the missing balance knob, any suggestions?
