power supply failure

[dave munroe]

One night the power to my 3B1 went out as if the AC line had been
yanked.  After checking that the fuse was OK, I attempted to power
back on.  All I get when I do this is the LED's on the keyboard
lighting up, going out, and lighting back up at about half-second
intervals.  Also, the speaker makes a clicking noise at these same
intervals.  No fans, no disk, no CRT.  Naturally, this is the system
which is out of warranty, no maintenance, and where most of my software
resides.

Does this sound like the type of problem that would require complete
replacement of the power supply, or might it be just some component
that could be easily replaced?  If it's the latter, how easy is it
to remove the power supply from the system and take it to someone who
could repair it?  I'd like to avoid moving the whole system.

I'm sure a whole lot of people would be interested in having third party
maintenance on the Unix PC, but I don't know of any and it's been a
long time since anyone's heard of Amperfax.
