This circuit was originated by GM3OXX, hence the name. It has become a classic circuit. It produces about 1W CW. It has been built by many people in many forms and is very easy to replicate. You just need to add a low pass filter for your chosen band. I have used it to 10m.   This schematic was on the G3PTO website many years ago.
