It's far easier to rewind than to redesign the mixer circuit. Best I remember it's about 25 or 30 turns of magnet wire. The only trick to it is you have to wind it in the same direction as the original. If you don't it won't oscillate. If that happens just switch the wires that are soldered to the terminals on the coil, not the magnet wire. Should work fine.

figure out what all those squiggly meant.
