Death by Audio Octave Clang

There was already a layout in the forum section but not on the main page.
This version should easily fit in a 1590B box.
Original FSB thread and schematic available here.

  2. I think the depth pot is wired backwards, but other than that, I'd call this one verified.

    1. level 3 is on your pot, it has to be the last unconnected leg.

  6. Hello ! It doesn't work, the LM741 (i used ua741) is not feed by the +9v, because no audio comes out the pin 6. Should the first 47uf capacitor have to be connected between row 1 and 3 instead 1 and 2 ?
    Thanks for your answers !

  7. Hello again, still not work, ive tried to build it again and my chip gets burned when i pluged it on 9v battery... i have checked few times during this days and i have noticed that the vcc- (pin 4) of the ua741 go throught the offset 2 (pin 5), so i add a cut between them plus a link for vcc- to the ground.
    Now it get sounds out but it's not modulated at all, density pot acts like a low pass filter and a volume.
    Anybody still here for help ?
    Thanks !
