I suspect you live in lightning country, Dave.? Southern California where I live is just about the least likely place on the planet for lightning strikes.? After damaging at least 2 instruments in the process of replacing (old) RIFAs, I'm not risking that again.? YMMV.

But I don't replace old RIFAs on sight anymore.? Too much collateral damage by a ham-fisted engineer with a soldering iron in his hand, and explosions are rare here in 120 VAC land.? Those in 240 VAC land risk explosions, though.
