Looks like the gas discharge type I have.
Somewhere I heard someone say that they go shorted when hit,
like a MOV, but that seems counterintuitive and it seems more likely
that they would just go permanently open by out gassing.
What's your opinion on this?


The instructions point out that this happens and that you can get back
on the air by removing the replaceable arc pill thingy. I suspect a
charge big enough to fuse the gap would have been a front-end killer. I
was a firm believer in Power MOVs when I was a station engineer in South
Texas.
