Tektronix 2247A scope fix?
 

Can somebody help me out? I've got a nice 2247A that was working fine,
but I suspect blew the PS since no lights, no fan, no nuttin' happens.
I turned it on and off several times ( I was looking for the source of
some RF noise) before it stopped working.
I have the schematics, but if anyone has run into this before and
could point at a particular area or part or procedure I'd appreciate
it, or even would recommend someone who is familiar with these 'scopes
and repairs and calibrates them.

This may just a simple problem with tantalums going high ESR or shorted, so
check for that first. If not you will probably need a service manual which
is relatively easy to get from vendors on eBay (particularly if you can live
with a scan). Artek, or QService spring to mind, but that are plenty of
others too.
