I have the ML-1 with wood case and extra modules. Unfortunately I have never been able to use it because I don't have the power supply. It was given to me years ago by a lady. Unfortunately I was not present when it was dropped off so I had no idea who it was. Two years after I got it out of the blue she dropped off a bag with all the cables and modules plus owners manual. Lucky for me I was present this time. I asked her if she had the power supply, her response "somewhere but I'm not going to look for it. If I come across it I'll give it to you." I told her I'd come look for it but her answer was no. It's been ten years and still no power supply. Only thing I know is her first name is Mary. Back then she refused to give me her last name, phone and address. The last power supply that came up on ebay sold for $1800. Way to rich for me at the time.
