    Hmm, well that shouldn't pose too much of a problem at the moment,
as I keep my System Saver plugged into a surge protection outlet bar.
Years ago I had the unit plugged directly into the wall, which is when
it probably blew that MOV.

    I suppose the surge protection is ineffective on both lines now,
both 'Master' (plug outlet 1 and 2) and 'Aux' (plug outlet 3 and 4)?
I do have a spare System Saver in the closet (in it's terrible
condition, yellowed and cracked) though maybe I can swap the
circuit board from that one and save myself the trouble of doing
some soldering.
