Brian do you have any photo evidence of an ot that was run without a speaker load, from one of your tear downs? How much damage can just a few seconds do? What are the long term affects of "just a few seconds?"
I want to kick myself when I do this, but it does happen.

So far, I haven't had a failure, just wonder if some ill effects will show up later.
