[QUOTE="MusicMan_ZA, post: 1100835, member: 14924"] Definitely a problem/component on my little DIY PSU PCB. When I feed in 12.6VDC to C1 - under load - it pushes out 0.7VDC. When I feed in 12.6VDC to C2 - under load - it pushes out 0.7VDC. When I feed in 12.6VDC to right before the output terminal block - under load - it pushes out 12.6VDC. When I feed in 12.6VDC from V-out of the LM317 - under load - it pushes out 12.6VDC. So an issue with (or my implementation of) the LM317 or the 5K trimpot. Will replace those, and see what happens.
