Hi there.  Think I have a dodgy PSU on an AV9000 control centre.  Super simple looking circuit so I guess it's a straight forward fix. Blowing fuses F4 and F5.  Looking at the diagram they both come off the same rectifier - I guess the rectifier is goosed? Other symptoms are no audio - I'm guessing there's no power going to the amp because of the fuses... Oh - and the main AC power feed going to this - does it matter whcih way round the neutral and live are?  Can't remember how they came off now.   Any ideas? Cheers
