RE: who uses different wire colors in amps?


+ve side of circuit: red
-ve side of circuit: white (or black)
Transformer to filaments/heaters: green

The exceptions are the AC runs to the power transformers, which are per regulations.

My next build will use different wire diameters depending on the stage (current) and purpose (hint: the ratio of signal to B+, local PS returns, signal returns).

AC filaments/heaters: tightly twisted solid core, large enough to carry the current plus some headroom (but not heavily over-sized).

Where the desired wire colour is not available I will use white wire, clearly labelled/coloured to leave no doubt about its purpose.
