I have an old RS machine that just quit. The problem is in the circuit board. I had two rectifiers and the condenser replaced that didn’t test out. We retested all the components and they all appear to be good. I am told that we can’t go further unless we have a circuit board diagram. HELP !!! does anyone know where I can get a diagram. I can’t get any return from the number listed for the manufacture. Wester Gem appears to be a dealer, but I don’t have a phone number or email address to ask them about it.
