Foprward / Reverse resistance is normally a reliable rectifier check.
However it will not indicate failure under load, if in question it would
probably be best to replace the device in question and the filter caps in
the same circuit. However don't attempt this after a couple "Fosters" Eh,
cheers gov.

Sorry, I meant a capacitance meter of course.

The result for all of them were very close to the specifications, except
the
one I replaced. That one was showing higher readings after I held it my
hand for a while. But I guess that is not much an indication. However
replacing it did change the symptoms slightly but did not fix the
problem.

Sound like a cap that is in the power supply. See if you can locate a
rectifier, or perhaps the four diodes that make a rectifier and
replace. A faulty rectifier can often stress a cap to the point of
failure.

Thank you, that sounds like an idea worth trying.

I can locate the rectifier no problem (a square bit with four legs I
think),
but I have a question since as you can probably tell I am still learning
as
I go along.
If the rectifier was for the power supply and it was faulty, wouldn't that
stop everything from working?

Or is it that since the rectifier is faulty, it immediately damaged (or
stressed above the limits) the new capacitor I put in?
Secondly, is there a way to test a rectifier to see if it faulty?

Thanks again for your help. I think there may be a light at the end of
the
tunnel yet. :-)
