I like your ms-paint work there gargoyle.
It's an interesting paradox... the one thing that has griped my ass over the whole following of Jeff's ideas... lead out surgery on transformers and chokes.
I've wrecked countless chokes and even done some damage to a nice power transformer.. Not to say the whole idea is stupid, but moreso I am just too aggressive when trimming leadouts at 1" from the transformer.
Even then, many times I've opened up the chokes and soldered the magnet wire directly to the new leadouts..then glued everything up.. most successfully with gorilla glue.
The problem is then that I have little confidence in the chokes durability when working on the new leadouts..and that bothers my OCD a bit.
Anyhow, the SILVER LINING. I was at work on a 7 tower AM array where we had trouble with a 220 volt 20 amp contactor that switched one of the towers in and out of the pattern. The problem was the leadout had broken off from the terminal strip. The other engineer being my equal or better at being destructive ripped the entire leadout out of one of the coils for this relay. $1500 to replace the whole contactor... or scrounge ebay for a coil for the 1960s EF Johnson contactor.
I burned the enamal off the magnet wire and soldered a new leadout on. Then I put a bunch of gorilla glue on the whole thing. Two years later it still works great. Drives me nuts, but hasn't failed yet! Ugly as hell but it saved the day!
Thanks Jeff!

That is very clever!
The poor guy was not fortunate enough to get the "cornhole torch" as that is reserved for the most elite of LSES builders.
I think his filter chokes were too high in DCR for such an honor.
Better luck next year.
