Just wondering if anybody has ever come across this before, The Vu+ Duo i picked up for my son to use whistles when its in use. The receiver works fine but the whistle is a little annoying.

I tracked the whistle down to the PSU. Any ideas what this could be. The receiver is knocking on for 4 years old according to the date stamp i found on the case under the psu. Its definitely a 100% genuine Vu+ Duo, not a clone.

I did buy a replacement PSU from a shop in London through eBay who does claim to be an authorised VU+ retailer but all that did when fitted was put the red light on and nothing else. I refitted the old psu and the Duo came back to life, although with annoying whistle intact. No idea if i was sold a clone psu i was sold, all i know is that it didn't work.

I would have rather have purchased one from WOS but they dont seem to sell them

I'm pretty handy with a soldering iron so i may have a go at fixing the original one if somebody can possibly point me in the direction of where to look first.

Thanks
