Apropos of hot chassis sets, be sure that the line
filter cap(s) are replaced with Y rated cap(s). Also,
I routinely move the switch to the plate side, and use
polarized plugs so that neutral is permanently connected
to the chassis on those sets. As they come, they
are either hot when on, or hot when off, there is
no safe way to plug them in. Moving the switch
alleviates that. I do that on all AC/DC sets, including
the floating ground ones. This runs a slight risk of introducing
hum. I have only had this happen once, and I fixed it
by rerouting the AC line, and making it a twisted pair.
