Wow. Thank you for taking the actual measurement, Wally.
I did a little more searching after posting yesterday, and Litz wire, is apparently, not all that hard to find. Apparently, we might need to know things like how many strands in the sheath, and the strand gauge.
Anyway, it looks like, if we had something on which to wind the coil and into which to thread the core, we could probably make some of these if we really wanted to.
From your measurements, it appears that a 3/4" long slug might do the trick, unless other Macs need a higher inductance range.
Any idea at what frequency this component is operating in the circuit?
Okay, I emailed TSC to see if the 1/4-28 series threaded core is available. It doesn't appear to be present on their on-line store. I guess more to the point would be to check the first link I provided and see if any of those already made cores fit the inductance range you listed.
However, the total resistance probably matters too. While you have the equipment out, would you mind taking a DC resistance measurement of the coil as well. From what I remember the inductance is pretty much determined by the number of windings (does the diameter matter? I can't remember), and one chooses the gauge of wire to give the desired resistance for so many coils on such and such a diameter.
