[Elecraft] oops -- repairing K3's KIO main board

[Ben Collins-Sussman]

I was installing the KVA transverter board this morning into my K3, and
stupidly had my finger in the wrong place while popping the KIO main-board
back into position.  One of the 4 capacitors at the top the KIO board
popped off -- at least I think they're capacitors.  I didn't recognize them
-- some sort of surface-mount transistors?  Some sort of op-amp or other IC?

After I calmed down from my panic, I managed to do a sort of hacky-solder
job to get it back on -- I'm not so good at surface mounting small parts.

That said, the K3 isn't reporting any errors, and after activating the KVA
module in the config settings, I see no error messages either.

Is it safe to assume my soldering repair worked?
