Good powersupply

This Powersupply is indeed very good when you look on its pricetag. Some people say that the both outlets that can provide higher voltage than 9V are not really isolated, I can't confirm that because I only use 9V Pedals. What I can say is that this item can power more than 5 Pedals for example when using an Y-cable or, like I do, powering another pedal with the output of a TU-3. The only thing you need to consider is that the total amount of power consumption per connection does not exceed the specified amount (300/500mA). No humming or other problems have occured with this, so I can recommend it for boards with not to many not to hungry pedals.
