Good old Youtube! I always do a search there whenever i want to know how to do something. I find it's usually a good idea to watch 2 or 3 different 'how to's as with certain things there may be differing opinions on the way to do it. Trouble is i get sucked in and taken off on a tangent and end up learning about stuff I'd never even thought of before.
I didn't realise youtube did that sort of thing at all.
Now have to work out why my speakers have failed, so I can nderstand what they are trying to show me
