I would like to use DC battery instead of AC transformer for power supply. Then I used +12v,+5v, -12v, -5V DC battery to replace 7805,7905,7812,7912 regulator. However, no response.
There are only 4 regulator inside the CD player which are 7805,7905,7812,7912 respectively.
What is the reason?
Any additional DC that I need to supply for the IC and other devices in order to operate the CD player?
