In Kennedy 92, the author gives a worked example of Chua's circuit experiment. The circuit diagram is given below: enter image description here

The author (in section 7.1) discuss how the value of each component might be chosen, except the inductor L. He uses an 18mH inductor. I don't know how he chooses this value.

What if I use a 15mH inductor instead, but keep everything else the same as the article? Will it still work? I cannot buy 18mH inductors...

The answer is within the linked PDF file.

This will be our starting point too, but with a slight difference. Electronic components are available "off-the-shelf" in standard values; 7.13 mH, 5.56 nF, 50nF, and 1428Ω are not standadrd values. Therefore, we choose 18mH, 10nF, 100nF, and 18000&Omega as a nearby "standard" value starting point.

Wouldn't a 15mH inductor be more "nearby" to 7.13 mH than 18 mH?

But why not simulate the circuit in LTspice or in Falstad?
