Is there a project page for this?
Why MN3002 instead of MN3005?

MN3005 is a 4096 stage BBD while the MN3002 is a 512 stage BBD. Later revisions of the Chorus Ensemble used 1024 stage BBDs such as the MN3007.

im pretty sure the ce1 never had mn3007
the original jazz chorus (stereo chorus0  amps had the mn3002  then went to  mn3007,, perhaps this is where this originates from?

 Back in the 1980s I built a CE1 using a TDA 1022 and whatever opamps I had.

You might've forgotten the footswitch holes in the drill template.

Help guys, how's it going?

I don't understand the wiring for the input and output jacks.



I understand the pads "L" and "R" are the outputs, is that right?
I have not idea about The pads "J1" and "MO".

This is from the original CE-1 schematic.




Please any help I will appreciate as I don't have the schematic, I only got the board and the pdf file that is in the post.

Leo.
