I have a 15-91 in the art deco cabinet and have only run it to make sure it works mostly because someone has put stuff on top of it but I want to get it so I can use it since I hear so many good things about them. Cannot thank you enough for all this great information, DonnaMiller! I think I will take your advice and buy the controller and light bulb you recommend. I have been a bit nervous about sewing on the machine until I get all the wiring checked out so this info is a big help to me. Did not realize that Sew-Classic had these items in their shop. I do know everyone raves about their products and service so I will feel comfortable buying from them. Thanks again!
