Via holes are holes in the circuit board that you don't put component leads
in. They are there to connect a track on one side of the board to another.
The electrical connection is made by a layer of plating that gets deposited
in the holes during the board fabrication process. Look inside the holes in
a board to see this layer. However, it's microscopically thin, and it is
even possible to have hairline cracks that cause the connection to be broken.
Anyway, all those tinier than normal holes left over should be filled with
solder, but not the ones for the pots, the tempco resistor, or the wires
coming from the board. Hold the board up to a light to see if you have
missed any.
Why doesn't Paul have us solder these holes for all the kits? I suspect
because this is a higher performance circuit, and a denser design, but I'm
sure he can tell you his reasons.
