Thanks, I get it. One for power and one for signal. I also have never had the chassis of any gear become "hot" and have used some pretty ancient, though well maintained (by professionals) tube gear in the past. Though, I did have a close call with a Hafler 500 power amp that I purchased used and owned for a short period of time. When I was checking out the internals after purchase I discovered a cracked connection on the integral power cord that could have shorted from tension on the cord in time, and since it was being used as a PA amp and being moved around a lot, Murphy's law probably would have prevailed. Fortunately it just required re-soldering.
