Steve,
Sounds about right. I will make up some and see how they perform. As long as
they don't mess up the primary function of the lead, this is a winner.
Hope that you are well!

They appear to be V10H40P (Littelfuse P/N) MOVs or equivalent, which cost about
$0.35/ea. Capacitor value unknown, but I'd use .01uF/1kV like the Vishay
75-562R5HKMS10RR or similar, which are about $0.70/ea.

What values would you recommend for the MOV and capacitor?
