If you have a BBC model B then at some point you will be replacing the power supply capacitors. Its a great machine but these three capacitors seem to cause an issue. If you turn on the computer for about 5 - 10 minutes then all seems to be fine but if you go over then you'll probably get what I had where the magic smoke got released.

The capacitors I used are from RS components and the sizes and models are:
