I’ve worked on the Empire heaters with some success at repairing them, although I’ve never fooled with the B-38 before. I would assume the heater is made the same way they are for the steam engines. Those are made with sheets of mica where the ni-chrome element is wound around one sheet and insulated on both sides with two others. The element is a very small ribbon. I’ve thought about re-winding the heaters with new ni-chrome wire, but haven’t tried it yet.
Joe, did you happen to purchase your B-38 from Shelby today?
