transformer Hum


does anyone know how to decrease this problem ?
My preAmp transformer hums (not through speakers)...
Is this because of my power supply ? I already have a dedicated line. Or is it because the transformer is going bad ?
would line conditioners help ?

thanks,
flying

Have someone check the rectifier diodes or bridge, whatever is used, and or power supply caps.
Good luck.
