chaos and odd inductor values

Hallo again,

the chaotic module i mentioned a few months ago is coming along nicely 
(at least on paper), and i'm dying to fiddle with it. but i can't find 
the particular inductor values (13 mH and 80 mH) it calls for, or any 
that will add up correctly in any reasonable quantity. all of the places 
i've checked so far seem to go straight from around 600 uH up to 100mH. 
some wacky series and parallel configurations are always possible, but 
i'd like to try to get as close as i can, since i know i'm going to have 
to change the values along the way as i modify the "paper" circuit.

for those that want more specifics on the circuit, i found a version of 
Chua's circuit 
(http://www.chipcenter.com/circuitcellar/august99/c89r4.htm#chaos) that 
doesn't just run in the normal autonomous mode -- the component values 
are kept constant, and with the addition of an AC source and a series 
inductor, the (sometimes chaotic) oscillations change according to the 
amplitude and frequency of the source. in other words, AC voltage 
control. whee!
