I have a technics rack system from june of 1992. It includes su-g91 amplifier, tape deck, cd changer, equalizer, and tuner. I recently moved and brought the system along with me. The rear wiring got messed up in the process and i can't find the org. manual that i had when the system was given to me. If you could find me a manual for that system or one similiar i would greatly appreciate it. Thank you.
