Tim,

 

This is a twin T that I use in one of my transceivers:

This fun to make but kinda raspy:

A Twin T is hard to beat, so is a phase shifter like Jim has in the MagicBox.
Simple and smoooth.

| Good evening gang. Well, we got plenty of snow here in central Illinois.
| In between other projects and naps I've been thinking about some
| different projects.
|
| Any suggestions for a moderately simple transistor based (vs. an I.C. of
| some sort) audio oscillator? I'd like something for a practice
| oscillator, sidetone, etc. that isn't all raspy and nasty sounding like
| a 555 timer based circuit. Doesn't have to drive a speaker directly, I'd
| just like a nice sine wave that I could couple into a separate small amp.
