Hi everybody,
I'm excited - finally I've got all my parts together (almost) to build my little PS. I'm hoping someone might have an answer to this question about ssltech's power suppy schem, for which I am ver greatful!
Here it is: My toroid will be 2x18v (20.9v no load), instead of 2x20 on the schem. I'm assuming this doesn't mean much to the +/-18v supplies, as the regulators are fixed. I did start thinking however that I might have have to do something with with the resistance on adjust of the LM 317. Then I realized that I'm not even sure how he's getting 48v out of that.
Here's a link to the schematic:

And here goes:
Are C5 and R1 setting the input voltage on ic3?
What will I recalculate for IC3, once I understand it, with respect to the new primary voltages?
Thanks folks, and sorry to bug.
