The Replica 1 uses two distinct power regulators that are not interchangeable and must be installed with the correct orientation.
I identify the two unique regulators correctly and put them in the right spots -- but rotated 180 degrees from their proper orientation. Thus the parts need to be desoldered from the board. This is beyond me, so Replica 1 creator Vince Briel and KansasFest attendee Paul Zaleski grab a soldering iron and a "solder sucker" to fix my mistake while I watch helplessly.
