Thanks! Good to know that is normal.

does anyone know if the LFO led is supposed to flash when the power is connected but the footswitch is off?

all of them seem to be seated well. but who knows? thanks for your input as I flail through another build.

Hi Chris, thanks for the excellent info. I'll do as you suggested and clean the board and reflow the suspect solder joints. then hopefully i can mark this one as fixed.

Update. I checked every resistor on the board and they were all good. then I plugged in the power and suddenly the LFO led started flashing. At that point I could dial in chorus sounds via the trimmer pot. yay! So it works now, but I didn't do anything to fix it. Which means there is a...

the staticy sound is back. the LFO led remains steady on. I reflowed the jumpers to no avail.

should I reflow the IC jumper pads? or since I have power that is not an issue?

on the pins. easier to get to.

that's the only 3101 I have right now.

THanks for the reply, Bio77. Unfortunately, no freq on the multimeter.

Hi Chris, thanks for the reply. I pulled the MN3007 out of a working chorus pedal (that had other issues) so I think it's good.

Hi Locrian, thanks for the reply. I swapped out the 4558 and got the same voltages. what should the voltages be? and how should I attempt to troubleshoot? thanks

Hi everyone, Just built a Cepheid Chorus. When I first tested it, I got a whooshing staticky sound. Bypass works. The led light comes on. The LFO light remains on, doesn't flash. I used a probe and got clean sound up to R24, right before the signal goes into the 3007. After the 3007 it was...
