Discrete audio amplifer project PT20.1 distortion measurement

The project amp distortion is finally measured! Due to the limitations of my equipment, the measurements taken at 20Hz and 20KHz read excessively high. The amplifier will have to be measured when the boards are made with better equipment. However, I'm confident with the amplifier's performance.
