Here is a crazy & bizarre question for the technically inclined. My girlfriend has developped a healthy fear of pretty much all of my guitar amps, but especially those that I've worked on myself. I made the mistake of explaining to her how dangerous the currents in amps are after she saw (and heard) me discharge the caps on one of my amps. So the question is this...if anything shorted, failed, popped loose, insulation was melted by a stray soldering iron, etc...is it possible or even reasonably likely that you could be zapped from outside the chassis after it's installed back in the shell / combo cab? Touching the chassis, knobs, tube holders, etc.? I'd like to offer my girlfriend an informed explanation about how this really isn't likely and how the dog isn't going to be fried by brushing up against my '69 Superlead.
