hi Dave I don't know what to tell you, I imagine that a direct discharge into the shack would have burned everything.
I had 6 USB cables connected to the laptop, they burned the USB of a box of GHE that costs $160 and the USB of the KPA1500 that costs +$7000 rotor controls and other PCs did not burn In short, it was the fear I had of buying new and sophisticated equipment living so far from where the company is located.
