Delkal,
I have been respectful to you but your attitude is poor and your knowledge worse.
The AC supply is a voltage at 60Hz. However the frequency of the power draw, i.e. current, is a factor of the load effectively modulating the line frequency. Hence you have current draw both at 60hz, and at many harmonics of 60hz, primarily odd harmonics the spectrum dependent on the load.
I will emphasize again a linear supply cannot work if it draws power only at 60hz and you are confusing supply voltage frequency with power draw frequency. The lack of knowledge is not mine, it is yours. (Note I said that it draws power 120 times per second not that is the primary spectrum of the energy draw).
Short of a resistive load just about nothing on the AC line has low distortion.
It would not be unusual for a linear power supply in a piece of audio equipment to be running 30% or more harmonic distortion on the AC input current. Only way to fix that is to add resistance or inductance to the AC input lines.
