[sdiy] LC osc for AF

[Toby Paddock]

Could someone point me to some 
Audio Frequency LC Oscillators for Dummies info?

I'd like to build some, but it's been too long 
since I did that in school and that was probibly 
RF and with tubes and I didn't really pay enough 
attention anyway and my books are buried in the 
garage somewhere.

The coils are on a rod core and maybe something 
like 10-100mH.  50mH and 2uF would res at about 
500Hz, but I don't even know if that's a 
reasonable range.

Interaction between oscillators with the coils 
near each other is a definite plus.

Don't care about a clean waveform. 
Don't care if it's stable.

Thanks,
Toby Paddock

PS- Unrelated, but does anyone use inductor 
saturation or hysteresis for distortion?
