I replaced two in two ASRON power supplies that got zapped with 220 and seem to be still working. I would recommend getting a good brand if you have the resource.

I have a ICE surge suppressor on in front as well but thought I would put more inside the supply for back up. Also, are the MOVs that radio shack sell any good. Rated at 130VAC. Any body used them... Last question: when MOVs fail or take a surge do they fail in a shorted condition taking out the fuse till the MOV can be replaced, or do they blow or fail open leaving the supply working. Thanks for the help.. 73s
