IMHO that defeats the idea of an isolation transformer.



That depends on where you connect the EARTH wire.
I was thinking of connecting it to EARTH.
What about you? Live? Chassis? Why not be adventurous
and connect it to that thick wire that goes into the side
of the CRT?


Perhaps you don't understand what isolation means? Would you also earth
one side of a mains isolation transformer in a workshop?


No but I'd earth the frame. Wouldn't you?
WTF does that have to do with the problem of the live chassis TV?
You can either have the headphone side of the transformer floating
at some voltage determined by the leakage capacitance, or stick an earth
lead on it (Not on the TV side!) and ensure that the sleeve is always
at 0v.
