Piggybacking an octave up circuit

[spaceace76]

I've been wondering if i can add an octave up section to any circuit, particularly a fuzz face or something similar.  
It seems like you can just add the transformer and diodes and create an octave up effect. While tinkering today i tried to do this, but bobtavia style with the RS transformer and 1n914a diodes. It didn't work, though i think it could be a wiring issue, but I'm wondering if you can just cut and paste this circuit onto anything, with no changes at all? It seemed straightforward at first, but now that it doesn't work I'm rethinking my approach  

any help is greatly appreciated

What octave up circuit are you referring to? I know you can make an octave up with two transformers - ie: a ring modulator fed the same input to both sides.

This works with any circuit where the circuit can do what it was supposed to do in the first place and also drive the added load of the transformer and diodes. This may not be a trivial load. You also have to get the AC and DC conditions right, so that the transformer, which is a DC short circuit for most purposes, does not foul up the existing circuit.

thanks RG! i'm trying this on a unidrive, and possibly a fuzz face, how well would that work?
