You're welcome. There are plenty of other filters similar to the one I
mentioned; it just happens that this one was a good replacement for the one
that failed in my system. For that matter, there are a number of other
suppliers. If you prefer screw mount rather than snap-in, that's available.
Integrated switches and/or fuse holders I assume are there as well, I didn't
look. Also various filter configurations and current ratings.
