Help please : CGS29 ver 2.2 partially working.

Help please : CGS29 ver 2.2 partially working.

2013-07-16 by ALFREDO

Hello, please I need some help.
I have build that module and half is not working, the GRINDER and LOCKHART works ok, the FOLDS, OFFSET and PWM doesn't do nothing.
I purchase the components kit from Elby Designs so I don´t think I make a mistake placing components values.
I wiring the module exactly the same way as the wiring diagram at the CGS web, powered at +/-12 volts and minijacks grounded together.
Maybe I´m not patching correctly : VCO to triangle or pulse in, LFO to VC folds and OUT to VCA, this way doesn´t do nothing, no sound at all.
Please any help appreciated.
Thanks.
Alfredo.

You have a construction error somewhere. Either there is a solder bridge
shorting out the signal, or there is a bad joint or break where you have
applied too much heat soldering. Have a good look at the bottom of the board.
