It's been 12 years since I designed the thing, and I really don't remember a lot about it. It may be the warble I was talking about. If changing the value of CA does effect it, I guess it is.
As for a 0V input, yes, it stops the clock. The following text is from the web page. I think the description is not quite right, as a 0v input simply prevents any more clock signals from getting through. The description suggests it simply disables that input, but I can't see how that would work.
"There is an over-ride condition where an external clock pulse is ignored. If one of the weight determining CVs is below around 0.5 volts, it is deemed to be effectively zero - in other words, an unwanted state. The comparator detects this condition and blocks the clock pulse, so the second multiplexer holds the previous state. This may mess up the perceived weighing of that particular state, but it is preferable to selecting a state to which nothing is connected, thus the unit can be used to switch between 2, 3 or 4 different inputs as required."

I made a small vid about it here :CGS 051 WRSCGS 051 WRSTroubleshooting the WRS (CGS051) The 4 CV OUT (bottom) are following each other closely, and doesn't seem related to the CV IN's (top) - Is this the normal ...Preview by Yahoo
Sorry for the bad quality - screen capture, but i think it might clarify some things.I'm only showing 3 CV IN's and 3 CV out's + the clock (I can monitor 8 signals max)I think the micro oscillation (making the CV out act as oscillators when amplified) is the "warble" you're talking about in the docs - so probably normal.The 4 CV OUT (bottom) are following each other closely, and doesn't seem related to the CV IN's (top)They also stop working when the weight knobs are set to 0 (fully CCW), despite the fact that the fluctuating voltages keep entering the CV IN's.
The vertical scale of the display is approx. -1 V to 5 VDoes this CV out behaviour look normal to you ?Thanks !Philippe
