Duo Phase whirring sound

[Champagneperfume]

Greetings everybody,

I recently finished building my second Duo Phase, overall the phases sound great, but I'm getting this weird whirling/clicking/rhythmic sound from the right phase. The whirling is slight audible when effect is engaged but once bypassed, you can really hear it come through. The speed/rate changes when automating the knobs. I've read that it may have something to do with the LFO being picked up with one of the conductive wires. I replaced the cables and I'm still getting it. Can anyone guide me? I'm a newbie but which component/components generate the LFO? Thanks in advance.

Try rerouting your input jack wire as far from the TL072 at the top as possible.

That was such a quick response, thank you so much. I'll give it a try.

No sweat. Here’s a crude pic of how I usually route my input wires on this build...under the board of course.

So I've wired my duo phase with the optional 4 1/4 inch input and outputs, I'm still getting the whirring sound. Should all the input wires be lined up like the picture above? This is a dumb question, but when you say "under the board", do u mean where all of the solder points are?

Thanks in advance, I got the effect working on both sides but I can't get the damn whirring noise to go away.

Yep!

Would using shielded wire on the inputs help at all? Still getting LFO ticks even with the wires positioned like the image you provided.
