Final update since I don't know how to delete a post: I traced the modulated audio signal to r21, which is where it stopped. I swapped out c14 to see if that made a difference and took r21 out of the circuit entirely. That seemed to fix the LED always on issue for some reason, but I still wasn't getting any signal. I noticed that signal went into one leg of the cap at c14 but didn't come out the other, so I pulled that leg from the circuit and took the probe to it directly and was able to get a signal.

Ran a wire from that leg to the output section of the switch and it's good to go!

Quick update:

I can hear it doing all the modulating on the resistors in the modulation section, and then the signal stops once I get to r21. I just tested the voltages and a few of the chips are off, so here are the readings:

IC2 Pin 2 and 6 go back and forth between 10.3-13ish. Tey should be be right around 7v.

IC4 pins 12 and 13 are both around 1.6-2ish when they should be around 6.7v.

IC5 pin 6 is 4-6.8v when it should be 14.8.

Q2 I'm getting swapped readings for the collector and emitter pins. So the Emitter is reading 14.2 and the collector is reading something else (forgot to write it down but it's listed as "varies" in the BOM). I tried flipping Q2 around but that didn't seem to make a difference, still not getting any signal out of it.

I also noticed that the BOM has r20 listed as 470R but on the schem its listed as 100R. I swapped it out to 100R but that also didn't do anything noticeably different.

Hey all!

I just finished putting together the Current Lover and am not getting any signal when the pedal is on. I've got it set to run at 18v with a 3007 chip. The LED stays on all the time, but gets a little bit brighter when the pedal is engaged. I took it out of the box since I thought maybe there was a short somewhere, but testing it unboxed still produced the same results.

I've also started taking an audio probe to it, and as far as I can tell most of the resistors towards the beginning of the circuit seem to be passing audio just fine. I'm also getting audio into and out of the BBD and am able to hear it modulating and changing when I move the rate, manual and feedback knobs in different positions, so I don't think the issue is in the chip itself. My guess is that it might be something power related, but I'm not really sure where to look or where to go from here at this point, so any help would be greatly appreciated!!

I've attached a couple pictures of the board in the google folder below.

Hey all! Hopefully this is the right thread to post this, but I just finished up a Dandy Horse build and am running into some issues. Basically it seems to be working in the sense that I'm getting some modulation out of it and the modes are "functioning" enough to know that there isn't any issue there, however I'm unable to dial out any of the high pitched whine that should be dialed out with the cancel trimmer.
The cancel trimmer itself seems to only range from "super intense whine" to "somewhat subtle but still present" whine. It's the most pronounced with the trimmer set in the center, and then gradually decreases the further I turn it left or right. I'm also noticing that the gain 1 and 2 trimmers don't seem to have that pronounced of an effect, unless I max out Gain 2 I don't really hear a difference between them.

I started checking voltages and everything looks good except for the 3007s, so I suspect something is up there. On IC3 my readouts are:

15v
7.5v
10.1 (should be 7.8v)
0
0
7.7-9.5v (should be 7.5v)
8.8-9v (should be 8.4v)
8.9v (should be 8.4)

on IC4 I'm getting:
15v
10-12v (should be 7.5v)
9v (should be 6.6v)
0
0
10 (should be 7.5v)
8.6v (should be 7.6v)
8.3v (should be 7.4v)

I've doubled checked all the resistor and cap values around the chips, reflowed everything in that area, and still can't seem to figure out what the issue is or how to get rid of the whine that's there. Any help would be greatly appreciated!!
