Switch mode PA Amp PSU fault

[Yorkie]

Thanks for the rapid respose to my query guys. I'll see what tomorrow brings! If a new cap doesn't sort it, I'll get back to the supplier to ask if they can supply a replacement PSU. The case came apart with just two screws and overall, it does look quite well built and designed, and rather more complex than I might have imagined. I guess that a lot of the 'gubbins' is to do with the battery-charging circuitry.
