I assembled a Jewel Thief as per the attached image and it worked fine.
I wound a center tapped inductor on a ferrite torus, about 20 turns and it worked fine.
The ferrite is about .75 inch outside diameter and .25 inch inside diameter.
Since idle hands are the devil's playthings, I disassembled an Computer power supply and found a similar ferrite torus with two windings each about 25 turns, which I converted a fifty turn center with a center tap.
I removed the original center tapped inductor and installed the newer one.
Again it worked fine, but I am wondering if this changes the oscillating frequency or operating efficiency or other (?) characteristics of the circuit.
Can't put a scope on it because I don't yet have one.
Thanks
