Hiya,
I'm just about to finish my CGS Wavefolder board, bought from Bridechamber. This seems to be a mix of the CGS29 and the newer CGS 67 active ring modulator when comparing this and this.

I noticed on the CGS 67 wiring diagram that Ken uses an pot for unbalance and there is also AC and DC ins. On my Bridechamber board there is just one input marked. Does anyone know if I can just duplicate the wiring shown on the CGS67 page plus add an extra 1uF cap to my Bridechamber board to get the same functionality shown on Ken's CGS67?

Also do I use the trimmers marked CNULL and IN NULL on Bridechambers board to setup the board the same way as Ken describes for CGS67?

Thanks in advance Smile

David

Hi David

I haven't built the Bridechamber version, most likely there are no major changes. Adding an AC input the same as the original cct should be no problem, maybe mount the components on the jack and run a wire to the other end of the DC input's 100k (the node between the 100k and pin2/NE5532).

also I would assume SNULL and CNULL would be the same to set up as per Ken's page.

Hopefully somebody with the Bridechamber version can chime in?
Very Happy

andrewF,
Thanks for the reply.

That clarifies things for me, back to the soldering Wink
