Vintage Pioneer Equipment

well, now i have another question, lol...... i googled the amp, and found an old thread on this site and the input signal to the amp is small red/white wires, which is curious, because the only thing i could see as speaker output on the head is really small(22-24awg solid) and over 3' long in red and white, or possibly the green and grey with the red and black, and the speakers are negative ground. the red and white wires look like they may have been added by someone. anyways, are you saying you have the service manuals for both of mine? or yours? and, can i get the wiring info, please. i think i may put both of these back into working condition as a pair
