Sanyo system 1020 and Sanyo CP-M2403.

Hi, everyone, I'm system1020 in England UK and this is my first post. I'd like to ask has anyone here got any circuit diagrams, ( schematics ) for the Sanyo system 1020 music centre made in 1982 and does anyone have a service manual for the Sanyo CP-M2403 multi CD player. Any help most appreciated and thanks in advance. system1020.
