"Dave Plowman Criminal Psychopath "

Phil Allison

Bet the Beeb et alia stopped doing that when they nearly electrocuted the
first guitarist.

1. The most common error in AC plug wiring is Neutral-Earth reverse - the
item works and there is no big problem until you find an AC outlet that has
Active and Neutral reversed.

2. Add a 240:240V iso-transformer that carries the supply ground through to
the outlet and it becomes instantly LETHAL.

Supply earth goes direct to one side of the amp's AC tranny, then the
iso-tranny's 240V winding and back to the amp's chassis. The amp will not
run - but the chassis is 240AC live.
