Re: CGS48 - VCO -- some questions

2006-03-09 by Jan-Ahrent Czmok

Hi all,

i got a bit further; it seems that the Problem with the "touching IC"
can be isolated to the pin 2/3/4 and the pro SP trimpot.
once i touched (!) the Pin 2/3/4 the VCO oscillates.

i successfully got audio of SAW+/SAW and SINE, however haven't looked
at the power neither oscillator view.

1)

I tried to run the VCO with a bit of CV1 in from an LFO, but this
does not seem to work either with or
without Pot.

2)

How do i need to connect the POT ? Middle Pin goes to CV (right
beside the PLS connector), left pin to jacket and right pin to Ground ?
Info: Pot is 100Klin, so as all pots are.

3)

COARSE/FINE. have a TUNE input and 2 pots (both 100klin). How do
those get connected ?
cause i got a "Tune" connector on the PCB and 2 pots.


Thanks again for any help ... Progress seems slow, but steady.

p.s.: of that what i heard from the VCO is superb (SAW/SINE) :-)
