The US convention is "white is life, black is death."



Funny though, in automotive, black is usually ground, and I've seen people
used to one wireing sceme crew up the other, usually someome used to
automotive electrics mucking up AC wiring.

Black ground is the electronic convention. Green is filament power,
red is B+. I forget the rest.

In the UK (possible Europe too), since the 1950s or even earlier, it has
been:

Red = H.T
Yellow = Anode
Purple = Screen grid (I think)
Green = Control grid
White = Cathode
Black = Chassis
Grey = Negative bias or feedback or A.G.C.
Brown twisted = heaters (well tucked into the corner of the chassis)
Yellow & black twisted = Loudspeaker
Red & black twisted = Mains
Blue & white twisted = 600 ohm balanced line
