Couple more minor errata in the manual.
1. On page 13, step 1 it says to install the #6 solder lug between the volume and the balance pot. It should be between the Input Selector and the balance pot.
2. There are all these 0.1uF 100V Z5U caps that we attach to the ground lugs. The manual is missing the step where it says to solder the ground lug connections once it is all done.
