capacitance with a 100VA transformer

Thanks.

Is it safe for me to increase the capacitance to 4400uF or, even better, 6600uF? I don't have the tehnical knowledge to work out the answer.

The reason for the query in the first place is that I have a VERY SMALL amount of hum, and have had this since the caps were installed (new) when the unit was built. I am hoping that increasing the capacitance will eliminate this.

Perhaps I should have added that the IR Hexfred rectifiers used in the PS are rated at 8A 600V
