Solder points on the top and bottom of the board.
Firstly I am an electronics engineer with over 20 years of experience in this field. It was a fun project to introduce my son to electronics. The board has several test points on some of the caps where you can measure the correct voltage and troubleshoot if necessary. Don't forget to solder the vocals and you will love this project.
- I look forward to
- Expensive insurance
