No hiss from speaker


Paul Cartwright
 

I have finished the audio amplifier portion of the build. I am not able to hear any hiss from the speaker while following the test instructions. The power circuit tested at 1.7 volts. I have double checked the components and connections, including comparing my circuit with the photos on the website. Everything looks correct. Any ideas on how to troubleshoot this problem?
