Hi,
I've just finished the build of the Haible Subtle Chorus. It apparently works. The effect is very subtle and I can't hear any difference between the modes. now I want to adjust the trimmers.
I understand that I need to adjust 5 trimmers:
BBD Bias, and BBD clock x2 for both channels and the LFO Offset.
I've got to adjust the BBD Bias and Clock, sending 1k signal to the input. But I didn't get any signal in the pin 7 of U14 that is for adjust de LFO.
I read a thread from an old Electronics Music Forum:
This is for a symmetrical LFO shape at pin 7 of U14.
Apply signal and check a point after the BBD (like U6, pin 6) for clipping. Increase level and adjust R15 for symmetrical clipping.
Without input signal, check wiper of R24 for remaining needles from clock signal. Adjust R24 to minimize these.
Anybody that have build the Subtle Chorus can help me?
Thanks.
