My QUAD FM4 keeps blowing the internal fuse. I believe this is a fairly common problem and is usually down to failure of the RIFA capacitor in the power supply. I've checked it out and it's definitely bulging slightly and has leaked and smells like it's burnt out! I've sourced a replacement together with a new memory back-up battery which I'm going to replace at the same time. It looks like a simple enough job, but I'd be interested to know if anyone else here on pfm has done it, whether they had any problems, and if there is anything I need to watch out for.
