I noticed something odd about Dave's assembly photo of the 485. If the
jacks are labelled like they are in the catalog photo: Left side top to
bottom: IN1, IN2, RES; right side top to bottom: 1V/OCT, FM, OUT, then
the jacks are not wired correctly. The photo show IN2 as wired to the
top, right jack, and a twisted pair to the middle left jack.
Accidentally reversed?
