It's nice to see another British member!
I've restored two Macintosh Classic II's and it would be worthwhile to recap the logic board and the PSU portion of the analog board.
It would be likely that the capacitors on the logic board have leaked. In my experience the PSU capacitors may have leaked.
There are a few tell-tale signs, such as a 'fishy' smell and the AB may look like is has had Coke spilled on it.
When recapping logic boards I prefer to use SMD electrolytic capacitors for that stock look.

As for finding SMD capacitors I usually type 'SMD capacitor' and its value.
Good luck!
