The problem seems to be with your bias voltage (called V/2 in the schematic). Pin 10 is directly connected to V/2 and you measured that voltage to be 0V, it should be half of the power supply voltage (9V/2)…around 4.5V. You can see the bias network in the center of the page on the schematic…it’s a voltage divider consisting of R10 and R9, along with C15, C10, C11, and C16. Make sure the pins of C15 aren’t bridged. Also make sure none of the other pins are bridged to anything and everything is soldered correctly.
