Hi Jonathan..

Just emailed you again;

Just had a real close look at it with a loupe, I can see a single strand of wire from the +ve very close to the –ve.. Reckon it may have been arcing.. Tried to take a pic for you but my camera/phone cant take pictures that close and all I could get is a blur..


Part of me is relieved as this could well be the source of my probs... You set the the PSU for two outputs, 65v 8amps which I am pretty sure is fine for those motors.. Yes please, if you can send me a replacement rectifier, I will solder it on.. The -ve wire is also crispy so will replace that too...

Steve..
