Do the voltages on the schematic indicate the powered-on standby values? I'm looking to repair the audio output of a amateur radio handheld transceiver...Volume has to be turn to max to hear it. Partial schematic attached. Q13 at the top of the image is the AF pre-amp. IC3 is the AF power amp, with pin 5 being the output going to the speaker. I've already tested the speaker and it is fine.
