@erik_squires Thanks for your thoughtful and detailed response. If I lived where there was lightning, I'd be full in on the best surge protection available for everything excep my audio system....I'd probably just unplug my Regenerator before each storm....I know, PITA but as you know, I don't even like the degradation caused by fuses.
I'd probably come up with some inexpensive equipment to use when lightning is in the area.
Difficult problem you have and I feel for you.
thanks,
Jerry
