The table is Grounded and the motor is grounded also separately.
But this is not the reason: the hum is there when the input of the phono is dead-shorted (it is 1/2" distance between the GND and the input of the tube so I short if with a screwdriver).
This is the tube and I am not sure what makes it hum. The power is super-clean.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
