Thanks for the welcome! I'm really chuffed with my LC475 find as I always wanted one as a kid. Here it is:

As you can see, minimal yellowing and all in very nice condition! I might well take up your advice on recapping the unit as it would be a shame for leaking caps to wreck anything internally. I think there's a company in Reading that recaps Macs (not confident enough in my own soldering skills to do it myself).
I don't hold out high hopes for the PowerBook battery to be honest, as according to my Dad it hasn't taken a charge for many years and doesn't even register in the computer. I'm thinking of removing the cells and just placing the empty plastic shell back into the laptop to avoid having a gaping hole. I only use the PowerBook as a bridge machine between the LC475 and my main computer at the moment anyway so it isn't the end of the world if it's tethered to a power supply.
Here's my current setup at home:

The vintage Mac gets pride of place as my distraction-free writing machine
