I'll report back once I figure out what's wrong with it

The RS-35A is not a switching supply - - in case that influences
anyone's thinking... I've got 2 of them here...

Typically, the linear style supply loses its pass xstrs or 723 regulator.
It also has a SCR over voltage protection on the output. Clamps the + to
ground...the fold back circuit in the 723 prevents burn up. If it hums when
turned in, I'd check that first. Remove the OVP and check voltage unloaded.
I have an Astron RS-35A here that is DOA from the lightning strike. There
might be some good spare parts in it, or you can try to fix it. Free for
pickup. I also have a couple of computer cases and other junque available.
Call or email.

Richmond is a bit of a trip. I would like to visit your
site anyway sometime though. Don't throw it out just
yet...
