SOLVED Cepheid Chorus No Chorus…

Just finished a Ce-2. I used a MN3207/MN3102 pair. I get no effect when the pedal is engaged, just clean tone. I know it’s a crap shoot with BBD’s from EBay, but I bought from a seller others have had success with. My issues is I’m not sure where to start. The rate LED works, and changes with the rate control. Does this mea the clock chip is good? Or does this mean the BBD is good. I imagine that a pulsing LED means the clock chip is fine. Am I correct?…

I LOVE the graphics on this! Great job!!
I'm attaching the Service Note in this thread also and how BOSS sets the potentiometer for both the CE-2 and CE-2B.
Question - it says input signal should be sinewave, 200Hz and +3dB...what would that equate to in voltages (e.g. - 1.21V, 168mV, etc)?!? BOSS CE-2 Service Notes_Page_1.jpg BOSS CE-2 Service Notes_Page_2.jpg
