Is the value of the inductor important in chua's circuit?
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 1428&Omega; are not standadrd values. Therefore, we choose 18mH, 10nF, 100nF, and 18000&amp;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?
