Possible Octavia Mod?

[Michael P.]

I was wondering if it may be possible to modify the Tychobrahe Octavia in order to get harmonics other than an octave - say a fifth, an octave down, or perhaps another octave up? I know an octave lower is possible with other circuits (Blue Box), but I'm mostly interested in what can be done with the existing inductor-type circuit.

Its a system of getting ring modulation so you are getting a lot of sum and difference frequencies, but it can't really get anything else with inductors.pl
