Screening and soldering:
Using sharp snippers I cut the dodgy capacitor body out. First it's a good idea to be sure you know the polarity and hopefully the value. I use a lamp and try and leave a long lead behind. Naturally you must not stress the soldered joint or it defeats the object. Clean the leads with surgical spirit. Put copper disk between the lead and board. Tin the lead. Take new capacitor and loop the leg to meke tight fit. Tin it. I then solder the joint. It should bite. I test the joint with the odd pull and finally between leg and board. It should be resistance free. It reduces risk to the board especially in this case where the leads had a slight hook. I've never had such a joint come off before on sets I did months ago.
