customer brought this one in today.
the red arrows indicate the failed and the blue indicate the larger values of caps, all others are the 330uf
2 obviously blown 3300uf 6.3V
total to replace :
5 x 3300uf 6.3V (yes)
1 x 1200uf 6.3V (yes)
8 x 330uf 25V (yes)
it would be best to recap also the 330uf as they are quite large sized caps with vents even though their uf value is less than 1000uf and would not normally be necessary to recap.
For those, i will use 1000uf 16V as I have seen TC using those for a similar job. I actually have some 1000uf 10V lying around but would prefer to follow a tried and tested method for a customers board.
well the 3300uf are going to look a bit ugly as the ones available are 12.5mm width. Here are the parts to be ordered from RS components, in case anybody is doing the same job i am posting what i will do as i think it out.
There are quite a few places on the board where caps are stencilled to be placed but were not. Therefore care will have to be taken not to solder a new capacitor in the wrong position.

3300uf 6.3V 12.5 W x 20H, 1.54 euro each, part no 449-0873
1200 6.3V 10 W x 16H, 0.54 euro each, part no 315-0259
1000 16V 10 W X 20H, 0.68 euro each, part no 449-0980
so that will be 13.68 euro actual cost but have to order in packs of 5 so total is actually 17.2 euro + shipping. worth doing at that cost because the cpu is an athlon 1000, still a reasonable machine for today.
