Hi! I build the SOST flanger and it sounds pretty fantastic. Some small debugging here and there but getting there. I do have one bigger problem I don't know how to solve. I have a 50/100 Hz hum.

The hum is always there (whenever the effect is on). But it get's stronger when the signal gets stronger. Here's a little audio example (https://www.dropbox.com/s/1tpejxf6muxz0 ... m.wav?dl=0). You hear it reacting to the volume.

I'm guessing it has something to do with grounding or the power supply?? I'm powering it with this power supply set to 15V https://frequencycentral.co.uk/product/fc-power/

I'm a bit short on knowledge here. This was an ambitious build for me. Already quite happy I got this far. Any help would be very much appreciated.

Thanks

How many modules do you have connected to the same power supply? Power supplies can get noisy when overloaded. Do any other modules have this problem?

Thanks for your reply. No it’s only powering the Flanger. It’s build in the case.

OK, then it probably is a grounding issue. Check the front panel wiring and make sure your grounds are properly connected to your jacks and pots.

Ok Problem solved. My walmart adapter wasn't supplying enough juice.. Fixed it.

One last thing.

On the Audio Connections schematic I see these open connections (mostly connected to ground I think.. SEE ATTACHMENT What do I do with these? Nothing? And if yes.. Why are they there.. I currently leave them empty and everything seems to work.. But just wanna double check..

Thanks

Just leave them unconnected. I think they're there because Jurgen envisioned several ways wiring could be done depending on how you implemented this device.

Done!
At least almost.. I'm getting some weird noise when the BBD2 switch is on "normal"mode. I made little recording. Just a simple sine wave into the flanger. I'm witching it from normal to inv. Pretty obvious.. Does anybody know what this could be.

Apart from that it works amazing. And I'm super happy!
