Good lord, what a Goldburg way of doing things.

Use one transistor in a phase-shift oscillator configuration and chose
your components for the same waveform ;-)

Won't work. He has the amplitutude ramping up and down at the beginning
and end of the tone.

Hi Leon!

Sure will, I've done it....by accident ;-)

Had a slow-starting conventional phase-shift oscillator once and decided
to "fix it".....ended up using the "flaw".

Changed the oscillator and adjusted the Re so you get a nice shaped rise
on the leading edge, cap from keyside to ground gives you the lead-out and
a little 1N4148 in the base-bias keeps her stable across room temprature
range from 15 to 25C.

IIRC, the xsistor I used was a 2N5088, replacing the existing 2N2222 for
more gain control.
