What is the purpose of this two pin component (circled)?
It looks to me like a jumper, but it seems strange that it would be so complex for just a jumper (that apparently does nothing). Sits between an AC input and a bridge rectifier.

\$\begingroup\$ Looks like you remove that part, could be interesting to see a photo of that configuration. I would guess it is for inserting a certain kind of current probe when testing, J11 designation is even weirder. \$\endgroup\$– PlasmaHHAug 28, 2018 at 10:41

It's a solderless spade connector, soldered to the PCB.

\$\begingroup\$ Any suggestions on why it was used there? I thought those things were for removable ground connections, which is not the case here. \$\endgroup\$– MastAug 28, 2018 at 18:47

\$\begingroup\$ @Mast, maybe it's used as an auxiliary power input for standalone testing of the board? \$\endgroup\$ Aug 28, 2018 at 18:49

\$\begingroup\$ @BrockAdams Perhaps, but I'd have expected another one of those in the other AC track if that was the case. \$\endgroup\$– MastAug 28, 2018 at 18:50

\$\begingroup\$ @Mast, it might be offscreen. Wouldn't want 2 AC lugs in such close proximity. \$\endgroup\$ Aug 28, 2018 at 18:52
