Default Rhythm king drum machine

Hi folks.
Does anyone have any service data or cct diagram for a rythm king mk1
Made in the USA 115v, has been got at, pcb with processor added to do somthing extra, insulation on the mains tx perished so I am fitting 240v tx to the power supply.
Soldering on past repairs is very bad, old carbon comp res, many are out of tolerance, lot of work to do.
John.
