That's right Richard. I have 2 chassis in my workshop with black soot areas where the AC line filter is. One is a Philco bakelite block and the other is a bumble bee that is split open and blew black dust over the area. Both units have the AC filter caps across the power cord before the switch. Better than a 50/50 chance that it happened with no one around.
