Chaos Machine LFO tick in bypass

[Woops is my middle name]

I recently completed the Chaos Machine - it sounds great, I love the effect, but unfortunately I'm getting the dreaded LFO tick, even in bypass. A dang shame, since I've completed several PedalPCB builds with LFOs - Sea Horse, Dark Rift, Phase II, Circulator, and Photon Vibe - and all are dead silent (save for some mild hiss on the P-Vibe, but that's another thing).

I've already moved the input/output wires around with no change. I've got lots of experience building kits but I've never had to fix an LFO tick problem until this build, and now the MadBean Glasshole I recently completed. Hopefully the fix will be similar for each.

Does anyone have experience with this?

Thanks!
