I would like to stop using batteries in my new Radio Shack digital AM/FM pocket radio - Cat. #12-587.
The radio is powered by 3 AAA batteries.
I am thinking I should be able to buy a simple 120volt to 4.5 volt transformer and hard wire it to the contacts of the battery holder, that is, just solder the 4.5v output leads to the plus and minus ends of the battery holder contacts.
With this set up I could listen 24/7 without replacing the batteries every 3 or 4 days.
Can this be done? What current output should the transformer provide at 4.5 volts?
I have a limited knowledge of circuitry and no understanding of resistors, diodes, capacitors etc. I did however manage to sucessfully build several Heath Kit items back in the day.............
Any suggestions will be appreciated.
