Oscillator Squeal/Whine - Low Tide

When engaged there is a squeal or whine clearly related to the randomize oscillator. It’s not boxed. I bought a real shallow water to compare it to... yeah i did. And it does the same thing. Is a diode malfunctioning? J201’s were mounted on adapter boards instead on the smd pads. I need to reseat the pots with the dust covers as I’m sure it’s shorting out. Help on isolating the whine would be appreciate.

A daisy chain power supply will cause noise in the other pedals so an isolated psu is needed.
 
Are you saying the unit you bought does the same thing? If so, it sounds like you have a power issue.
It does, however, I opened it up didn’t see anything amiss, reassembled, and it sounded fine.

I do have a problem with AC at the wall but when using an EHX, Triad, and Donner psu the same noise happened. I’ll try it with the isolated AC outlets. A Svisound pedal that had a color changing LED introduced a similar oscillation/whine until I disconnected it.

I realized this should be in Troubleshooting. 🤦‍♂️
