Subject: Re: Pop goes the PSU

I need to replace the filter caps on a model b PSU which went pop a few day
s
ago. There are two filter caps on the board, the one remaining reads 0.1uF.
Not sure what the other one is as the casing has gone on the capacitor.

>From an earlier post on this board, someone mentioned the maplin codes for
the filter caps, see SC93B and SC89W respectively at ...

http://www.maplin.co.uk/Module.aspx?ModuleNo=26584

These caps are 0.1uF and 0.01uF, are these the correct replacements for the
two filter caps ?

Just thought I would double check before soldering them out.

Which components do I need to dis-charge before working on the board, and
what is the best way of discharging them ?

Regards,
Paul.
