W8 a minute

I wish I would have known this a year ago. I had one of the original DD1's and it bit the dust. They offered to fix it a year ago so i sent it to them. A few weeks later I received the repaired unit. I went to use it only to find it didn't work correctly. I threw it in my toolbox and went back to using my Oscope. For a year I've been telling everyone it was a piece of junk. I tried it today using the negative to speaker method instead of the original negative to ground method and it worked perfectly. They might want to make this known in thier videos.
