Re: Winding quality of tricoils


Hi Gerard,

I'm not sure it makes a big difference.  I've not measured myself anyway.  However when I wind them myself, I do try to get them a bit neater looking like you do.

I would get rid of the third winding if it is not used.  I think they were just done that way for economy (only one kind of toroid to wind for all the transformers) and not for performance.

More important, look at the Wiki here for the RF power mods and Allison's revisions to the winding of T8, T9, and T10.
