MIT Z Stabilizer ll ? operation ??

Call Joe Abrams. He is on agon. He knows Mit better than anyone.

Thanks Drjoe, you're right about Joe but because he has a business to run I prefer not to trouble him. I'm hoping there are some techie types reading.

Actually, I would appreciate the same answers, as I too, own this unit and have noted sonic benefits but have absolutely no idea how this unit would work.

Your kind words are gratefully accepted! The key to MIT Stabilizers, in general, is less about filtration (although they do an excellent job) and more about Power Factor Correction. In residential AC, the Voltage component and the Current component are rarely in phase with each other. This makes usable power LESS available. The ratio is called Power Factor. In Power Factor Correction (PFC), the Current and the Voltage are brought more into line with each other, and, therefore, the power transformers of your system "see" more available power. PFC has been used in the industrial world _almost_ as long as AC has been available. Bruce Brisson was (is) a pioneer in using PFC to improve the performance of residential (and studio) sound and video systems.
Hope this helps. Joe

So, is it compensating for inductive or capacitive loads, or both? Does it have a bank of capacitors or an inductor (or both or something else)? Mine (bought a LONG time ago), has a toggle switch, presumably for different conditions (current leading vs lagging) but no way to determine which position to use other than setting by ear. Is this the case with all models?
