 I have an ancient Chang Lightspeed CLS3200 power conditioner that I use for some light duties. It is currently configured for 220VAC (factory reconfigured from 120VAC a couple of decades ago). Now that I want to bring it back to 120V territory, I would like to have it reconfigured for 120VAC. I asked the manufacturer and they say that it would still work fine, but there would be no surge protection. I believe that it is likely because of the MOV values (there are three of them), which are now 14MM ZNR V14391U, which are supposedly 390V. That, I suppose, would be too much margin to do anything in 120V territory. There's also some handwritten words in the unit that says the fuse should be 15A instead of 10A. Going back for a factory replacement of parts/board would be out of the question cost-wise for such an ancient unit, but it would be best if I can continue to get some surge protection out of it. What would be an appropriate value for replacing the three MOVs (a part number would be much appreciated)? For the fuse, Should I get a fast or slow blow 32mm 15A? Thanks.

Does this MOV look right to you? Thx.
