Failed in the middle of a measurement last night - no display, no

LED, a few red LEDs on the front panel come on intermittently at
power-up. The familiar burnt smell coming from the back, but no
smoke.
The enclosure felt a a bit hotter than usual immediately afterwards.

The incandescents on the graticule working fine though, and
they're fed
off the negative PSU rail, but the positive low-voltage supply is
definitely down for the count. I haven't had a chance to open it
up yet
but hoping it's an easy fix...

Too much going on with the holidays and work the past couple weeks to
have a chance to take an afternoon to sit down with it, unfortunately.
Paid work has to take priority. Don't worry, though, I'm not tossing it,
it's in my "probable PS-fault" section (along with the poor Korg
MS2000.) ;-)
