Dont fix it if it aint broke.
If your 1200 is working fine dont touch the caps.
The first you will know about a capacitor leak is when your machine stops working because the cap has eaten the track.
Change the caps NOW before it leaks too much and causes real damage. Prevention is better than cure.
(I say this having just fixed an A600 whose caps had been left. It had destroyed one track and damaged many solder joints). The first symptom of the failure was the floppy drive motor not working, by which time surgery was required. If the caps had been changed before, it would have been far simpler than tracking down the broken track. Incidentally the track that was broken was one of the data lines between the CIA under the drive and the rest of the board.
