If you look at a Dentron 2500 amplifier on the cct diagram the 230v
mains cable, WHITE wire goes to the ON/OFF switch on amplifier then
primary of HT transformer which to me is HOT and BLACK wire goes
directly to the other side of primary winding, NEUTRAL and GREEN to
chassis.
In the UK the switch is always in the LIVE (hot) wire and NEUTRAL
direct to the appliance except it happens to be a double switch.

UK appliance BROWN live, BLUE neutral, plus an earth wire (3 wire
appliance)

I have a USA amplifier with 230v input. The mains wires are
BLACK, WHITE, and GREEN

The cct diagram shows White as the live wire with amplifier mains
switch in this line, Black goes to the other end directly to
transformer primary
and Green to earth.
but
according to USA info the Black wire should be Live and White
Neutral.

So beware !!!!!!!!!!!!!!
