Default Re: AC/ DC radios live chassis.

Whilst both the human body and electricity are unchanged, public attitudes to risk have now changed a lot.

AC/DC live chassis radio and TV sets though in general use for decades, are at least a bit risky by the stricter standards expected today.

Before USING such a set I would strongly advise making certain that the neutral goes to the chassis, and that final connection is via polarised plug and socket. I would also advise that such a set be turned off at the socket outlet when not in use.

Before WORKING ON such a set I would strongly advise use of an isolating transformer, or at least an RCD. If a set being worked on is to be left unattended, then I suggest either locking it up, or removing the mains plug.

The fact that such precautions were not normally taken decades ago is of little relevance in today's more safety conscious world.
