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 !!!!!!!!!!!!!!
