Gary,
One thing to check is the tightness of the screws for the supply output
terminals. If one or both are loose, I recommend removing them
completely and cleaning the contact points on the inside of the power
supply. Tighten everything else up too while you are at it.
You don't have to work on a live power supply - unplug it first.

Good morning Don. The PS suddenly died on me at our beach house in Long Beach.
I had no equipment there and first
assumed it was my K3. Brought the rig home to Portland and it worked fine.
So, it was the supply, an Astron RS35A--couple years old.
Anyway, checked the fuse, cleaned contacts etc and it was .8v at the
terminals. . So, I replaced the voltage IC which I got from
Mouser and used Deoxit on the the voltage adjustment pot. I have another RS35A
which has run fine for over 30 years.
I don't feel comfortable playing around inside a live supply but will take the cover off and do another visual inspection while unplugged.
It has to be something simple I would think.
