You want to keep the machine as oriignal as possible by replcing the

You enjoy fixing thigns rather than replacing them. Rmember I routinely
repairr cooling fans to component level. I've repaired switches and light
bulbs too :-)
The type that looks like deep IEC socket
behidd the panel is probably not repariable.
In any case, about 80% of the different variants have equivalents which=20
are still available off-the-shelf... repairing a mains filter assembly=20
really is pointless IMO. In the other 20% of cases, you can usually make=20 minor modifications to the wiring (usually by
adding/removing wire=20
links) to allow the use of a standard filter module.
The Solartron 7150Plus bench DMM is a good example of this. The stock=20
filter module is a Schaffner part which is basically unobtainable on the=20
UK market at a reasonable price (RS did sell them at one point, for =A350=
=20
plus VAT each).
I assume this is one of the modules with voltage selector contacts? Is it
one of the ones with a little PCB under the fuse that fits several ways
round? Or one of the ones with a plastic camshaft you cna fit in sevearl
orientations? Or what?
I've found that the filter units on those tend to come apart fairly
easily -- they're not potted and the metal can is easy to unsolder. You
cna then repair/replace the filter.
Any port in a storm, right?
Well, provided it;s not USB :-) (Sorry, couldn't resist)
