In sending Roy the information on the markings I
omitted what looks like a
"~" after the 250V marking (the casing fragment is damaged in that area), so
Almost certainly the mains filter capacitors then...
the caps are probably rated for 250V AC. I can also
see an X2 marking on one
of the caps (the other one is too damaged to see). As the damage is indeed
to two caps on the mains filter, I have purchased replacements which I will
be fitting this weekend.
OK. If you replace like with like (same 'class', rated for 250V mains [1]
and about the same capacitance value) you should have no problems.
[1] Most filter capacitors sold in the UK are good for thsi, for ovious
reasons.
The rest of the PSU *appears* to be in good condition but I do not have
anything to test ESR with and I do not have a variac or the knowledge of how
to use one, so I am unsure whether I should attempt to connect the PSU to
the mains again or whether I should attempt to switch it on. If I do feel
brave I will only connect a load that I do not care too much about.
Personally, I would connect it to the mains with dummy load (car bulbs
or simuilar). I think it'll be OK.
