Double check on the Ring Lift switch when playing around with it, see below note on this in the build docs: Ring Lift (toggle switch) disconnects the ring (middle) terminal of the Time jack, which is equivalent to the “C” solution in the user manual under the “Time Out” heading without...

Thanks man, I really appreciate your advice and support on this - I am no good in this part of troubleshooting, never had the chance to go this far :) I was inserting signal from the input end rather than jumping the output path hoping I can skip the part it gets to the BBD board - and somehow...

Good luck man, I really hope it's something simple in your case - a lot of troubleshooting advice in here for you to go through

As a quick update - and kind of a journal for myself - checked all resistor values around, everything is good. I desoldered and double checked all transistors with a component tester, all checked out to be fine as well.

I can't bias it unfortunately - not in a normal way at least with signal coming through main input jack. No matter the trimpot positions there is no modulation appearing. I checked chip positions, transistor orientation, diodes etc - only thing I haven't checked yet are the resistor values...

I checked that many, many times hoping I switched them around :) they are in right places - unfortunately :) I'll do the probing once I get little more time with it and see if I can find anything obvious

No worries I don't plan to go full dissasembly mode XD I was placing them with enough care that I am 99.9999% sure I have all the right values in correct places including polarity / orientation etc. I never played much with audio probing but I guess it's time to wrap a cap on a jack and start...

Read it back to back multiple times now, same for Aion build docs - I still take steps back and try to think abt anything I could have done wrong here so just checked all my resistor bags to measure and check whether I don't have something mislabeled - I am not measuring each component before...

What I am starting to fear is that the JFet specs make a difference here, or at least some of them do and you can't throw random J113's in and wish for the best. I once built a harmonic trem based on a Catalinbread that didn't work until I started swapping J201s with other JFet transistors - if...

Hearing back from @Synchrony Pedalworks it seems all the LEDs (internal and external ones) are working fine - he's got a working build and checked that

Glad to know the LED3 is working as it should. At the same time it seems the issue is elsewhere - and reflowing everything on the board including sub board and 3PDT boards did not help. In my example voltages seem more or less in the ballpark - I think they are affected by some settings like...

Ok thanks and I very much appreciate your willingness to help here :) We're all struggling to understand the magic juices that run pedals ;)

Im not skilled enough in reading the schematic to tell what drives the voltage sweep that makes the LED pulse, perhaps it's something different entirely and this one should not pulse at all? I don't see the VD circuit being referenced for LED3 in the schematic and I might be bad in reading these...

Yes, this one works fine - generally from all "pulsing" LEDs including the 4 internal + Time / Space external, it's only internal LED3 that does not pulse, just turns on & off following Time footswitch.

no, still the same issue as when I started. I meant to say the connectors between PCBs seem fine

good luck with yours, I tried to go slow and be cautious to avoid trying to fix this mess but I guess you never know when your time for "what went wrong" comes

For now I reflowed all connectors and it all seems fine - I also checked for continuity from both ends (main PCb and sub PCB for each of the pins).

Yes Yes, it gets 7.58 VC, same as LED 1 - only difference LED1 is always on and starts pulsing when I engage Space fswitch, LED3 just turns on when I engage Time and doesnt do anything further

Thanks for the reply! Tried all of the above but still nothing. Trying to exclude potential issues I disconnected the CV jack and trig / gate jack - build docs mention these are not needed and no jumpers are needed also. I also reflowed all joints on the main / sub PCB connectors.

Hey, hope I can ask you All for a bit of help and / or advice - Finished this build yesterday... and surprise surprise it doesn't work :) I've built 150+ pedals and never ended up with a build that doesnt work (including couple Aion Lovetone builds) so I really hope I can get this one working as...
