Half Hertz very low level oscillation?

"Alex" wrote in message

If there is no negative feedback circuit in the
amplifier, then there is no reason to suspect coupling
via power supply as a cause of the phenomenon.

Where did you get that idea?

If anything, negative feedback reduces the effects of coupling through the
power supply.
