Hello,

I've just finished the build of a Stereo Chorus unit.

http://jhaible.com/legacy/subtle_chorus/jh_subtle_chorus.html

And I need to check if the LFO section and mode selection switch works properly, because I don't hear any changes between modes. When I change the mode I hear more "emphasis" on the effect. I attach a video. I don't think this sound is normal at all.

I inject 1khz to the input.

I attach a the LFO section and the rotary switch wiring section.

Anybody can help me? please?

are you fully conversant with the tabbed washer that stops positions around the switch bush? if so, please ignore the following - to set the washer correctly for 6 positions, you need to remove the washer, rotate the switch counterclockwise as far as it will go, and only then fit the washer with the spigot in hole 6. rotate the shaft and count the clicks, to be sure. then the A should switch 1-6, and the C switch 7-12.

also - we can't see the rest of your build.

The stop washer is in position at 6, this are ok.
