I'm having a difficult time getting my newly-built B1 to work. I only connected right in and right out to test. I get power to the board but the only sound I get is buzzing. I've measured all the resistors, the 1M at R200 measures 20k with no power (I don't even have the left input wired). The 10ks at R2 and R3 don't give a steady measurement (the measurements fluctuate without ever landing on one value). I've replaced all three with the same results. Is this normal when they're in-circuit even with no power? My solder connections look okay so I'm at a loss. I've attached pictures of the completed board.
