	Wonderful, I and the 2 others who asked me to forward anything I 
might have learned thank you. =) Now another silly question for the 
lot of you.. I would like to build a dirt-simple oscillator... no need for
voltage control or anything, just something that could put out a sound 
and live on a (9v? lithium?) battery without eating too much of it. 
Waveform is irrelevent, though I'd prefer something with more harmonics than 
fewer.. and I don't care how precise its shape is. The good side is that 
linearity and tolerances are out the window. =) 
	What I want to do it put it in the box with the ring mod, and use a 
normalled jack to allow a mod input for the ring modulation, but to have this 
little beauty there when I have no mod input. Make sense? It'd need one 
coarse-tune pot to control pitch. Does any such circuit exist, can one be 
made up quickly, or is there someone here willing to design one for an 
appropriate fee? It's not a major longing, but it would sure make my 
little ringmod box a little more versatile, and save me the trouble of using 
up a whole synth when all i want is a constant pitch sawtooth-wave 
modulating a 606... Thanks in advance!!!
