Having a new look at my inoperative 450w power supply (H7291-AA they are getting harder to find and expensive) I discovered that power entry module (ie: the plug socket) is not a 'straight through' unit but contains filtering circuitry).
The item a Schaffner FN321-10/0 (as far as I can discern) is faulty and trips the RCD switch in my home (with nothing connected downstream).
The casing has a small bulge and I seem to remember this PSU going 'bang' - which suggests a capacitor (i think) failure.

The original type unit is no longer available but I aim to try a later replacement, such as :
https://www.mouser.co.uk/datasheet/2/355/FN321-1-05-Schaffner-datasheet-9818449-1201765.pdf

I wondered if anyone has any thoughts on the subject - the sockets are only about £10 here and are getting the full mains voltage (230-ish here) and it would be 'nice' if they are a common reason for PSU failure and understandable.

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
