    My choke (Hammond 194F) has a black and a red wire. In my theoretical world it wouldn't matter whether it was connected one way or the other to the circuit. Is there a practical reason why they would give the wires different colors? Am I missing something?

    My vintage Blackface Fender has 2 black wires. Not sure why it would matter, but what do I know?

    My ClassicTone choke had two black wires. Classic, for sure. :)

    I agree with your guess, Tom, they're equivalent, but I await enlightenment from the wise ones...

    Only a guess- Much like Leo fender, they had or got some red wire cheap or were running low on black..... Others with more knowledge will hopefully provide other applicable answers.

    maybe test it. hook up to a headset and put it next the your power transformer. distance and orientation matter. I'd set it in a spot that makes a noticeable hum, then switch leads

    I've used headphones to find optimum positions for choke & output trannys, funny I never thought to switch leads. kinda doubt it will matter but who knows. now I gotta try that

    Either wire will work. Can't say why they would use two different colors but I like koolaides theory. It's just one long wire coiled up around a bobbin, with a hookup wire on each end to connect it into the circuit. You can use it in either direction with the same results.

    There is a *start* and *finish* to any winding. IDK if it makes a difference with a choke. I do like the proposal from @dogmeat to check it out.
    Hey, the inner and outer make an audible difference with capacitors so maybe.

    so.... I put a small Fender choke next to an 18 watt Classic Tones power tranny and couldn't tell any difference by listening. I hooked up the O-scope and there was no appreciable difference in induced voltage when switching leads.

    This is very edifying for rookies like me.
    Thanks for the effort!
