    hello.may I ask why the circuit of the first one didn’t work?I created a pcb design of it and now I don’t know how to troubleshoot it. By the way, I used a 8ohm,5watts speaker and the battery is 8 volts.thanks.

      did you test it on breadboard before you made on PCB? If it works on breadboard, then it should work on PCB also.

    Is there a substitute I can use for the 33 micro farad capacitor? I only have 22 or 47 micro farads.
