Your good, I just accidentally ran across this CTM in the Ford CD looking for something else.
Got to keep this in the my memory bank---if it would only stay where I filed it or is remembering where I filed it.

Oh yeah having two (or more whatevers) to swap parts and compare, makes it whole lot quicker/easier Eh? Or is A?

I've spent many summers in the UP and talk to many Hams in Canada. I like using "A", it seems more personable. Just my friendly opinion!
It sounds like this CTM module might be a good candidate for a "Mov" install on it's power input????
I've have had good luck with using 3ea 130la20a's in my 120 AC outlets. Neutral to ground, hot to ground and one across hot and neutral. Back in 1981 lighnting hits the Hydro (as you call it?) All devices that where plugged into those protected outlets never have failed. Everthing else in the house was zapped or died weeks or months later. I was convinced. However I don't have much experience with DC circuits, the thing I've noticed that telephony vendors in the early 90's started applying these to their plug-in cards/modules & etc.
