20V PSU Build Links

Link wires

For the link wire, I am using this lovely thick copper wire that was recycled. With this type of wire, there will be negligible voltage drops and one can be assured of good electrical connections within the circuit. In many ways, it is far better than a printed board... However, it does take some time to prepare and install the wire. I made all the links that I needed first, and then installed them in one at a time.

Diodes and Capacitors

The very short links (2-holes distance) in the bridge rectifier section should be placed slightly higher, this way; you can hook your probes to them during testing. Those two points are the DC output of the rectifier.
