I think the schematic I was using is wrong for the +48V section. The Cs are not doubling the V, and the 317 is not implemented properly.

apl said:I do get >50V coming off the rectifier but I'm getting >50V off the transformer. Maybe the designer knew that would happen.
OK, another look makes me think the 317 is OK. Nuts.
And I was an EE major. Never used a lick of it since school.
I'm learning a lot.
