Notes

All capacitors are SMT unless otherwise noted.

Sizing

There are only a handful of different types of capacitors used, so sizing is consolidated here:

CapacitorSMT packageApprox Length
47uF @16V2412 (6032 metric)5.5mm
10uF @16V1206 (3216 metric)5.3mm
1uF @50V1206 (3216 metric)5.3mm

128k/512k/Plus Analog Board

Common problems:

Pin 1 of J4 on the Analog board frequently has a cracked solder joint.  Reflow.

L2, which adjusts the width of the display on the screen, has a core that can crumble.  It is a an adjustable choke inductor with a threaded 1/4-28 powdered iron core that is about 3/4" long, inside a threaded plastic tube, allowing the core to be rotated to adjust its position within the plastic tube.  Around the plastic tube is a coil of litz wire.  When the core is completely removed, the value of L2 is 7uH.  When the core is completely centered in the coil the value is 33uH.  A nominally adjusted L2 value can be in the 25uH range.  The resistance is 0.066 Ohms.  There is quite a bit of variability L2 needs to account for, which is why it is adjustable, and the same values will not work for all boards.

Notes on the IIx power-on circuit, if your IIx doesn't power on with the power button but does power on with ADB:
