Thank you very much, thats very helpful to me.

Im quite electronically minded myself. Though I don't know much about
what these componants are for, I know a bit about how to find the
correct replacement parts. Unfortunately, there are only 3 of these
products ever shipped to the UK.

Is there anything I can do to detect a blown cap? I have briefly looked
inside to see if any of the caps have popped, but didn't see anything.
Does this mean I need to take it to a specialist?

Thanks
Darren
