Worked exactly as you all said it would! connected 4 core telephone wire to 0v 18v 0v 18v.
soldered middle 2 18v 0v to neg other 2 on to other pins . Both pins have 18v ac now!

I can't thank you enough.[/QUOTE]
Ive ran into the same problem with my alesis multimix 8 usb. I dont mind building a power supply myself, I just dont want to end up buying the wrong components. Was wondering if you remember what all you purchased to build yours. If you can help me get thru this, it would be much appreciated. Thanks.
