How the hell did it get into that state.

You can use any 1% Polystyrene cap of 120pF in that position as long as the voltage rating is above the Vcc of the IC. I'd go for 63V just to be safe.

Here's one as an example.

You might find these guys more helpful with small quantities but this is only a 3% component not 1%

Looks like it's been burned by having a soldering iron to close.

Ebay purchase maybe ?

Easy enough bit to get but nothing on E-Bay this afternoon.

I've never known one to fail though. OK this one is cooked, but they normally fail very early in their life.

I meant the Rotel actually, sorry if it wasn't clear. There's no way a cap could fail in that location and it does just look like external burn marks tbh.

I wonder why he suspected it in the first place ?

I'm out of my league here but if the IC is suspect - I would start with the Xtal.

The capacitor was fine until ,due to it being late and me being tired, i caught it with the soldering iron whist doing something else? Oh well these things happen.
Thanks again for your help.
