Hi guys! I'm after an 18V power supply for my Fulltone Fiulldrive 2. Instructions say must be regulated and centre negative. There are many out there and no idea if any good and they are expensive! is this type ok? Would it work? http://cgi.ebay.co.uk/Universal-Lapt...item2559d7df27 Or can you please point me towards one which you know is quiet (using a generic 12v one now and irt is noiiisyyyy) Thank you.
