Schematics for Dyna Comp model DCF 353 power supply (Apple LC III/Performa 460)

[tonata]

Does anybody have the schematics for this power supply? I could not find one.
My friend tells me that with the voltages I get there can be a problem with one of the transistors, but we need the schematics to understand it better. There are 3 transistors in general.

Apple part number is 614-0028.

The problem with these supplies, and the motherboards they're attached to is leaking capacitors. They both need a complete recap before anything else is done with them.

Also keep in mind after you've recapped them that these PSUs will normally tick/crowbar without a dummy load.

I have fixed many of these. I have lots of LC models. They use the same power supply. They all had leaky caps to the point they were WET and smelled horrible. A thorough wash and a recap fixed them all.
