33 kV!.. Whatever was that for electrostatic speakers or an AM
transmitter?...

The audio transformer was used for telephone wires that ran around the
country underneath 33kV powerlines using the same pylons. Every now
and then the 33kV wires would fall down on to the telephone line and
the telephone girls used to complain about their telephones exploding.


One of the regulars on uk.telecom ~20 years ago had an incident
where their phone cable snapped in bad weather someway down the
road, and the loose end blew onto 33kV conductors (not on the
same pole). Their phone and several other things blew up, but
they were unharmed. There was a Health and Safety investigation
of the incident.
