If you don’t need synth drums, you can simply tune the Twin T up and use the circuit as a sine wave oscillator. For a single set of capacitors it’s not very widely adjustable, but if all you ...

It’s a piece of test equipment that produces a low-distortion sine wave output, and would still be of use to an audio engineer today. He replaces the capacitor with two modern ones on a multi ...

The recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy,” discloses a low THD sine generator which led me to dust off a design that I ... Even if this were possible, the ...
