Hi
i have one problem in Amplifier, i am using transformer 12-0-12V 3A, 12-0V 1A. 12-0-12V 3a for Amplifier which is ok, and 12-0V is connected to 7805 regulator. this 5V supply goes to micro controller (digital volume control section) & usb driver section. when i gives microcontroller its ok no problem but at a time when i connect to usb driver amplifier hums & 7805 heated more upto it damage. any idea what is the problem?
