Analog Chorus on MN3207 from Russia

[Valentinych]

Some time ago, I talked about the project analog delay: http://www.diystompboxes.com/smfforum/index.php?topic=82708.0 .
I hope my chorus on MN3207 will also be of interest to someone.

That's really cool man,why not making an Arion sch1 clone at this point?

[Valentinych]

I'm sorry, but I do not know the device Arion SCH1.  

You can link to his scheme?

Excellent!  

Now I can not write the samples. I will try to write in the near future.

this is great because it has a tone control in front of the mn3207,its overall similar to any Boss ce2/3 and can sound really goodas a leslie with distorted sounds.
the only problem could be the true byass,being stereo,eventually the led could be operated otherwise.

Thanks, alehradium!

I had a goal to make a simple device that can be repeated by anyone. I did.
Other schemes choruses the internet a lot, and everyone can choose for themselves what they want.
I do not think that the stereo chorus is very relevant. Few has two channels of sound for guitar.

I look at PCB and I look at schematic...
What happens with R25?
On SCH it goes from power to IC3.5+IC4.1. But on PCB it goes from power to IC3.4+IC3.8.

Резистор R25 не туда идёт на плате, если сверяться со схемой. Так же микра не запитана, не?

I see that too. It looks like if you cut the trace between R20 and IC3/4 and jumper between that end of R20 and IC3/5 you would fix that issue. I didn't look for other problems.
