Well I’m going crazy here. I cannot find a combination of currently available cables or adapters to power the H90. I have a Fender Engine Room. I have available 2 9v500mA outputs (2.1mm). So I need a current doubler cable. Then I need to convert that to a 2.5mm plug. And also switch the polarity to center positive. So I need three cables with the correct female/male plugs. In what order?
There is a Gator cable that does two things- doubles the current and ends in a 2.5mm male plug, but it’s still center negative.
