Thanks helps a little but really need the schematic of the power supply
thats prety much what i have in my manual, except that one look german, and mines in italian. i thought it had more on schematics than shown, but it doesnt, mostly its instructions for the conversion i guess. sorry i cant help any more, these machines are bloody rare.
