* Leave the washer and nut on the rotary encoder. I took mine off thinking they might be used to secure the control to the front panel and then realized the shaft wasn’t long enough. Then I worried about the mechanical stability of the encoder without the nut/washer and took the (difficult) front-panel assembly apart again to put them back. :-)
* IC11 Voltage Regulator is not in the documentation parts list.
* Might be helpful to cut/trim a corner off the top nut under the volume control with wire-cutters to allow the control to sit flush to the board. I ended up using a blade knife to cut it off after installation to take stress off the control. (Pictures posted to QRP-LABS builders Facebook group.
* Stereo jack connectors don’t quite align with the holes in the PCB. May take some torquing to get them straight. Best to lightly tack two pins with a little solder to hold them while you bend them into place applying a little heat as required. Need enough force to straighten them out but not enough to break them. :-)
