Wire hunt.
(OP)
Would you guys point me to a source for magnet wire. I need,(GAHW&^%!!) 13AWG to wrap a switcher toroid.
I only need 10 feet for protos not a $600 roll.
Suggestions?

They are good about sending samples or supplying small rolls.
A suggestion; four conductors of 19 gage wire is easier to wind than 13 ga. Also less resistance increase due to skin effect.

You can get a half pound spool of 18AWG and it only has 100 feet (you'll need 40 feet per sreid's suggestion).
RE: Wire hunt.
sreid; This is a switcher inductor wrapped on a 1" dia toroid that will run around 125kHz. I need like 28 turns. Still recommend 4 - 19s? I look at MWS(wow) they have a bazillion types of insulator. I will try to keep this thing in the - under 90C range. What would you suggest?
zapped; With sreids suggestion I could now probably get 19AWG anywhere [Beldon],(if it doesn't suffer from odd-number rarity disorder like 13AWG).

You can wind with 13 ga wire but your fingers will be sore. It's a disaster in production. And skin depth is shallow at 125 kHz.
