I have a Sony Legato Linear amplifier (OK it's very old like me !) which has developed a crackle now and again. This seems to originate from the volume slider. Was wondering if there is a fix for this, I think I recall a spray to tackle it from the outside, if not is it possible to dismantle the case etc.

For decades I've sprayed WD-40 inside and it works fine.

I'd definitely go with dismantling the case before you start spraying anything inside an amp. You want to get the fluid where it's needed rather than missing and just making a horrible gunky mess.
Contact Cleaner (A.K.A. switch cleaner is the stuff you want)

He said it's a slider so it's easy to squirt WD-40 inside the potentiometer. Use it sparingly. No dismantling required. Should be good for a few more years.
I wouldn't use switch cleaner. It will remove all lubrication and make it worse in the long run. I don't even use it for cleaning switch contacts. They really need a film of grease or oil to prevent oxidation.

whats wrong with a switch cleaning lubricant then?
works well for me, I use this, and just normal IPA for other, non lubracative (is that even a word) , uses (which is all "switch cleaner" seems to be anyway

It's probably fine but it's generally not available locally (unless you have a "Maplin's" store nearby) so it's going to cost you between £3 and £5 plus postage. WD-40 at around the same price, dependent on can size, tends to be easier to obtain locally and most people have a can at home. It contains a petroleum based degreaser and a light oil.
