I have admin and moderator rights as well. I have never used the "Move Posts" function, but I think it worked.
Re: Boss DM-2 pcb variants.
Nice, thank you Pepe.
I posted in the photo thread thinking it would be just one post, but it grew and was polluting a bit the photo thread, here the posts are all right.
Please, delete now the posts 7th and 10th, they are in double.
Once again, thank you very much.

Re: Re: Boss DM-2 pcb variants
Hi everyone! I want to build the first version of the Boss DM-2 pedal. I managed to obtain a PCB that was created by someone and is based on the first version with the MN3005 chip. That is exactly what I want to build.
I checked the photos submitted here, and I verified that PCB exactly matches that of the first version. There are 2 little differences though, but I suspect those were made with a reason. The creator of that PCB is unknown, so I cannot ask him about this. But maybe you can suggest why the mod is there.
The essence: the PCB is like the first version, but the D6 diode is also added that was present on the last version of the pedal only. And also connection points 8-10 on the top are connected on this copy PCB with a part named CF. But there is no list of parts available, so I have no idea why it is there. Originally it is not on the first version either. I guess it is some kind of filter. If you have any clue about why these were added I would appreciate if you let me know! Here are the images to show the difference:
The copy PCB with the holes fore the D6 diode from the last version of the DM-2:
The D6 diode is this one from the last version of the DM-2:
The CF added:

You will need to register, but he will solve all your doubts and probably will help you to build the pedal.
