In that case, 7200/512 = 14 kHz; our frequency is 14 kHz.

Using a 4060 in this circuit offers significant advantages; it can simultaneously serve as an audio oscillator and generate a virtual ground—this is definitely worth considering. To ensure the MOSFET stage is accessible for everyone to build, it could be implemented using the TLP250 or TLP350, which are widely available on the market.Comment
