Hey,
just built the Cave Dweller 2, I tried it before on breadboard and it worked, but then I soldered it to the board and now it doesn't work.
It's strange, because the signal goes trough, and I hear it, I'm even able to change the volume with the volume Trimmer, this means that the signal actually goes trough, but it's unchanged, it comes out unaltered.
Any ideas what the Problem could be?
I'm pretty sure to have soldered everything right, could it be caused by the IC? or the transistor?
Any help would be appreciated.
Just out of curiosity, kill all the power, and pull the 2399s. Put them back in out, try again, they can lock up sometimes. If that doesn't work, pics f both sides and voltages will help you and us.
I finally boxed it up, love the sound.
The problem was the voltage regulator 78L05.
I just replaced it and now it works
