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.
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 !
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 !
Hi! My Octave Clang isn't working. By using an oscilloscope and an audio probe I found out that the 1n capacitor is swallowing all the audio. There is a good signal at the input side but than nothing on the opposite. Changing the part doesn't help. Any suggestions?
Hello, This schematic works fine, but I hear a "POP" every time I switch it on. Anyone with the same problem? Best regards and thanks for your hard work Francesc
looks very interesting. Had a quick google for transformer. Ebay £20 each , Mouser £2.10 each just incase anybody struggling to find one
ReplyDeleteI think the depth pot is wired backwards, but other than that, I'd call this one verified.
ReplyDeleteThanks Brandon!

but where is level 3?
ReplyDeletelevel 3 is on your pot, it has to be the last unconnected leg.

100nF caacitor should be added between VOLUME 2 and OUTPUT ;)
ReplyDeleteDo you mean attached to the middle and 3rd legs of the level pot?
DeleteOnly reason I ask is because I've built the above schematic a couple times now and am quite satisfied with the sound.
