Cgs synth

Hello
Ive completed the sub osc, and everything seems to work fine except
for the prescaller. As soon as I enable it, I loose audio on the B
channel. As usual, Ive checked the obvious (solder, polarity, etc).
I dont have another 4017 to try right now, but will order one if you
think that could be the problem.

let me know if anyone has any ideas.

thanks,
Scott

I know the switch could be a source of trouble, so I have removed the
rotary switch, and hard wired A to C and /3 to com. It does not work.
Im not exactly clear on how the 4017 works, but from what i can
tell, if everything else is working, the 4017 must be the problem.
Let me know if I am wrong here, and something else could be causing it
to fail.

It was the IC.

Speaking of the SUB OSC has anyone considerd adding this DB-120 Daughterboard to the
CGS Sub Osc, acually you could add one per channel. Here is a link to the board.
