I was just given the Alesis Multimix 8 USB but my friend had accidentally thrown out the power supply with some other old electronics. As it would turn out, this is very hard to find. There are no after-market power supplies made, as far as I can tell. The specs are 18V 500 mA and here is a picture of what I need: If anyone out there has this kind of power supply I will gladly pay what I can. I don't have a lot of money, but just let me know what sounds good to you. or if you know where I can get one that will work I would greatly appreciate being pointed in the right direction. quickest way to get a response for anyone who has one they can sell is to e-mail me at email@example.com Thank you for anyone who can help.
