I made a Colpitts Oscillator (06A-20) that oscillates at 261 kHz!


I mimicked one of the circuits that's been on Wikipedia since 2009. https://en.wikipedia.org/wiki/Colpitts_oscillator

The part number shown in the picture is wrong. The correct part number is 06A-20. This will be corrected in the next revision.

For ease, start with the shortest components.

Note the outputs are not inverted, and one is stronger than the other. The PCB silkscreen should be updated to only have one output (OUT+).
