I found this function generator in a scrap yard and bought it for just ₹10. The front panel looked fine, but when I opened it I saw that some parts were missing and it clearly wasn’t working.

Instead of throwing it away, I decided to repair it and understand how the circuit works. The board has sections for waveform generation, amplitude control, and TTL output.

In this project I will document the repair process, identify missing components, and reverse engineer the circuit if necessary. My goal is to bring this old function generator back to life and learn more about analog electronics along the way.
