OK that is one case where your need two failures to cause a hot chassis.
Now for Doofus to get electrocuted he will also have to have one
hand on this deaf radio and one hand on the radio that has a metal
chassis that is plugged into a socket with a good ground. The problem
you could also have a similar problem even if the neutral was wired
correctly (not tied to ground). If the ground wire broke in the cord or
inside the radio and then a capacitor or a transformer had an internal
short to the chassis or there was a resistor from hot to chassis ground
then the chassis would become hot. The so called safety ground is not a
100% sure thing in the case of a failure. Because safety grounds are as
prone to fail as anything a third external wire tying all metal cabinet
radios together is the only safety measure if one has a table full of
these old AC powered beasts.

Yes it is not a good policy to tie the ground and neutral together. I
just felt that a good explanation of why not to do so was required
instead of just a blanket statement stating "The safety ground must
NEVER be connected to the neutral at the load !NEVER! "

But he on the safe side and ground those boatanchors together. (you can
buy a bigger boat that way).

Doofus, likes to unplug his FT101E whenever he isn't using it, and he
likes to
windup the cord to look just like it did when the radio was new-in-the-box.
After doing this for a while, the neutral lead breaks. Doofus plugs
in his radio, and trys it out, and it works just fine! Doofus continues
operating this way, and eventually, another wire in the cord breaks. If
that wire happens to be the hot lead, the radio will quit, and barefoot
Doofus will take the radio back to the squire for a rewire job. If that
wire
happens to be the safety ground lead, the chassis of the FT101E will now be
at full power line potential (current passing from hot lead through the
radio's
circuits, to the chassis/hot- connection), and barefoot Doofus will be
pushing up daisies.
