[Shotimes] What the.... *poof*

[James F. Ryan III]

It's a variable-resistor so it's not really opened or closed.  At low
voltages the MOV has a very high resistance, passing very little current. At
high clamping voltages the MOV has very low resistance, causing the voltage
surge to travel into the MOV suppressing the applied voltage.

I suspect Doug's is permanently "open".  Like Paul said it should not keep
the circuit from functioning because MOV's are wired in parallel not in
series to the circuitry it's trying to protect.

Doug, I went to the TDK website where you can do a search on partial part#'s
and it came up with nothing.  It might be a custom run they did and not a
normal production unit.
