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

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. It may be that easy of a fix. The
linear series are easier to repair IMHO vs the switchers

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

Most of those switchers have an MOV and a low-pass
filter on the 120 AC input. This would be an easy fix
if that's all it is. I would come and get it except that
Richmond is a bit of a trip. I would like to visit your
site anyway sometime though. Don't throw it out just
yet...

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…
