Mine too, and now ... the real reason for this inquiry - why do you need one? Coincidentally, as you mentioned in the preceding message, they claim NOT to use an RFG. Which technically does not mean they do not have a fair amount of RF noise in the reactor, does it? It means only that they have

Why does everyone assume the heater elements use DC? A transformer would be the easiest way to adjust the voltage or current to larger rms values and would explain the isolation transformer. The blue control box then might simply gate this AC power through the transformer for longer or shorter
