Amiga 500 Power Supply Schematic (Brick) 110 Volt or 230 Volt

[AmmoJammo]

why do you need a schematic? there's really not a lot in these, either a part works, or it doesn't, if it doesn't, replace it?

or, are you trying to build a psu exactly the same from scratch?

The negative 12volt rail comes from an LM7912 negative voltage regulator, which regulates a higher negative voltage down to the -12volt, in your case, the regulator has shorted the input to the output... if you can't figure that out without a schematic, you shouldn't be attempting to repair it...

you have the power supply, why do you need a schematic?
