That makes total sense. So when the voltage is too high, the resistance of the varistor drops and the amperage over the circuit increases enough to blow the fuse. Never knew!

So does that mean the varistor may have been destroyed (even though it still looked fine) before the fuse blew when the previous owner put 220V on it? When you say they have high voltage when they go...
Thank you, that is very insightful. I think though that the varistor burning out is my doing earlier today: I'm quite sure it looked fine before I plugged it in. While the person I bought it from did...
It says 120 VAC 3.5 Amps 50/60Hz, same as my other unit which is working with the step-down converter. Is the Hz rating what you were referring to?
How can I find that out? Worth noting is that I have another US 8x10 processor that does work fine off the same step down converter.
Hi everyone,
I've been using the time in lockdown to go through my unfinished projects to complete them and I've come across my Polaroid 8x10 processor that seems to be cursed and has been sitting...
Great, thanks! Like this one? I never really understand how sellers advertise these. Is it inside diameter of the cap or outside diameter of the cap? The rear element seems to be 63-64mm outside...
Hi everyone,
Some time ago I purchased a Xenotar 150mm 2.8 mounted in a Copal 3 shutter but it unfortunately is missing the caps. I know the thread diameter on the front element is 77mm, but I...
