I have had to purchase not one but two of these regulators from Grace for my Janome 1600P that I use on a quilting frame. They don't last long at all. The first one starting cutting out and dieing while I was quilting. Ordered a new one. Now it's cutting out and at the end of my edge quilting it won't shut off until I have to pull the plug. At $69 each this is getting expensive!
Yes, you do have to have one that is compatible with your machine's two or three prong plug in. Anyone ordering one has to know this for the order form.
