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.

The same thing could be done digitally by a fast microcontroller. I think it
would be quite easy with a software DDS.
