Hi all,
I've recently tried to build a stock cmoy amp following tangent's online tutorial. However, I seem to have produced a 1lb solder weight.....
Anyhow, the problem is that I get very faint music for output. Unless I attach both alligator clips to the input post(i.e. capacitor post) then I get very loud sound equivalent to the pcdp. HA.
I checked voltages for the power supply and they came to 3.73 on both sides. So I assumed that is not the problem.
I double checked the resistors with my meter and they are fine and matched.
Also, the sound will stay on even with the battery unplugged so I assume the circuit is ok but the opamp isn't getting any juice??
Please help. I sure would appreciate any further troubleshooting advice so that my 2days haven't been in vain. I've attached two pictures to try to show what it looks like....thanks again.
