Build guide - It's best to populate the PCB in height order, smallest first.
1. Install and solder all resistors.
2. Install and solder all 1n4004 diodes. Ensure correct Polarity
3. Install and solder 100nF capacitors.
4. Install and solder all three LEDs. Follow the diagram on the PCB to ensure correct
polarity.
5. Install and solder 78L05. This part is not indicated on the PCB, it's right next to the
+15/12V LED. Ensure correct polarity.
6. Install and solder 10uF and 100uF capacitors. Ensure correct polarity.
7. Install and solder 2K multi-turn trimmers.
8. Install all power headers.
9. Bolt LM317 and LM337 to their heatsinks, install and solder. I find it best to solder
the middle pin first, which ensures against solder bridges.
10. Install and solder all 4700uF capacitors. Ensure correct polarity.
