Where live chassies banned on Australia

Many people died in Romania trying to repaier live chassie sets!
I can use a protection transformer or a transformer if you want to have a set like this, in order to don't have the phase of the electricity network on the chassie.

Ideally, the cabinet of this sort of set should completely insulate the user from the hot chassis. And also, the RF input F connector should not have a direct DC (or 50Hz AC path to the line as well. If this is done well, hot chassis sets are perfectly safe.

Of course you should use an isolation transformer when you service such a set on the bench.

Well, usually Soviet sets had a transformer, but my vintage one is an exception: it haves autotransformer, not transformer, so there is the risk of live chassie; and the thing only works at 127 or 220 V - is not the model that also works at 110 V (I have an 220 V - 110 V transformer at my home). The Romanian "Electronica" Naţional V.S. 43-614 that I intend in the future to get me, haves no transformer, but works at 110 V or 220 V, so I can use the transformer that I have.
