Hello, I have the following problem.
I made a clone of a Boss CE-1 chorus pedal.
I have tried to make the problem visible through videos. Hence the links to Youtube.
However, I have the following problem. When the pedal is activated, I get a lot of noise on my signal. This seems to 'dance' along with the chorus effect.

I did another measurement, and then you can clearly see that the supply voltages dance with the chorus / vibrato effect.
In this video it is measured on pin 8 of IC2. This is the + 14V. This is the AC voltage on the 14V. You can clearly see that the AC signal responds to the effect.

In the following video I have drawn out the time base and zoomed in further on the signal.
The yellow channel is -14V (pin 4) and the blue channel is + 14V (pin 8)
I assume that the power supply should be kept as clean as possible. Why could this be? All help and tips are of course welcome.
