Working again now smile

I replaced the power supply with the 40W version from Farnell and the 1000uF capacitors from eBay. If had had realised they also needed replacing, then I could have ordered them at the same time as the power supply from Farnell. The power supply took 24 hours to arrive, the capacitors a week!

And I remembered to set the power supply output voltage to 5.00v cool

I've kept the blown supply and hopefully will find time to analyse it and work out which components actually blew. Will post any findings here.

Thanks again everyone for your help
