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.

I'm not sure about this. Where have you seen it?

[njkmonty]

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?

[thermionix]

I think he means the CE-2.

[njkmonty]

yeah your right

[StephenGiles]

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

Where is it possible to order a pcb?

[xaxxop]

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.
