Looking at the schematic vs the construction layout there seems to be an error in the bass section (at least to me, though I must be wrong). The schematic clearly shows the signal after the 0.82 inductor going to a 6.8R resistor, passing through the 6.8uF cap to ground. The "as-built" layout, has the cap BEFORE the resistor which goes to ground. What am I misunderstanding? Thanks

Functionally the 6.8 cap/6.8 resistor combo can be either way around, it doesn’t matter which is first. It probably makes for an easier layout to arrange the components as Troels has. But a note in the documentation to confirm this would have been nice.
