We had a direct strike at one of our locations where it took out a number of electronic devices. During the damage audit, I flipped on the main amp rack and fans whirred to life on the stack of iNuke amps I had spec'd a few years ago. Smoke rolled out of one so I shut it down and pulled it out. Once insurance was tallied and the equipment was disposed, I took the iNuke amp back to the shop. Upon opening it, I found a single clamp diode at the speaker leads with a smoky crack across the top. I fired up the soldering iron and popped it off the board to see if it was holding the amp in protection. Plugged it in and - hey it's working! So while it's not lightning-proof, it sure didn't receive the kind of damage I had expected. It was the result of inductive coupling from the speaker wires that run through the roof plenum. The power side was untouched. I had installed an isolation transformer and surge protection at the panel. Looks like I was right on the money. But I still get to keep the amp.
