Default hum in pas2

i've just finished placing alps 250k pot for the volume control and eliminating the loudness and the balance control.
when i turn the vc totally counterclockwise (to the left) i get a strong steady hum which doesn't exist while listening to music.
any suggestions what i did wrong and how to fix it ?
thank you
