I don’t know enough about electronics to know the reasons, but parallelling the LDDs apparently maxes out at about 1. Robin hood country, UK Ldd-000hw Originally Posted by perkint. Technical Notes View more Technical Notes.

Aside from oscilloscope to monitor LF ripple characteristics on the output once the drivers were wired in parallel, would it be enough to watch the amperage on a multimeter to make sure the current didn’t start fluctuating to values higher than the max emitter spec?
