Hello, I realise that this should be a simple query for those in the know, and that's why I'm floating it here for some help. I need a replacement 12 volt AC mains adaptor 2500 MA with 5 mm circular plug to fit an external USB hard drive. Having some real problems identifying the best places to obtain such a part. I imagine they're available on dabs but I can't for the life of me find them on the website. So if anyone's got a direct url or even one to sell secondhand, the information would be greatly appreciated. Thanks, because I can always trust this list to come up trumps. Colin F
