I bought a never used JJ Cress Electric kiln it’s a B-18-H 240V and cannot find a manual for it. It has 2 manual dials. The company Cress said they are not the same company so I guess this is from the 70’s?? And company is not longer in business. I have 3 other kilns but they are digital Skutts and I don’t have a clue on this one.
