Dear Gragory.

you can find schematics on request directly (PM)to Dr. Bob, in order to know if D6 is the right zener, I dont have any DD but schematics and diagrams are extremely useful to found and test any part of the circuit inside our pedals, it could be helpful in your case because you are not sure to have circuit complete, and probably you will need to rebuild your PCB tracks with wires or soldering mat.

Im pretty sure you have another thing inside damaged, probably it just the PCB Burned track or maybe flipflop transistors ( if it has)it might be producing a short circuit that is causing a warn battery,I say this because my experience, recently I bought a damaged CS-3 and it had zener ok, but flip flop transistors were burned....

BTW, Do you have signal ( sound) without pressing pedal, I mean, is bypass working?

Hey, I am having the exact same problem as Goran. I plugged in a podxt adapter unknowingly (apparently the wrong polarity) and the pedal started to smoke, and smell like burning electronics but i didn't notice it until about 15 seconds after i plugged it in :(. I removed the D6 zener diode. I have a dd3 third generation (the bottom pedal at the site comparing the different models of the DD3). A few questions:
1) Does anyone know if this was the right diode to remove from this model of the dd3? The pedal still doesn't work with the zener removed. I removed it by melting the solder around it.
2)Do I have to add more solder as it appears it looks like the circuit is incomplete where the zener diode was.
3) Is there anymore damage that could be done to the pedal other than just the zener diode blowing?
4) If i put in a 9V and press the switch the light doesn't turn on and no signal is passed through, but the battery will heat up. Is this an indication of anything?

Thanks for your help.

Hi there folks, I haven't read through this whole thread, it was just the first Google search result I picked. My DD3 got fried when I used a power supplied that a salesman at the Source Electronics gave me, assuring me it would be perfectly matched. My mistake for listening to him! Anyway, I understand that diode D6 needs to be replaced. Here's a photo of the part on the circuit board. I carefully de-soldered it with a 15W iron and removed it and need to find out where to get a new one. I have no clue about testing it. I'll come back here to read the whole thread sometime very soon. If you have any suggestion where to get a new D6 I would love to hear it. Cheers, John (you can see D6 near the center of the image)
