I have an old radio (well... maybe 10 years or so) which the CD player is faulty, and tape feature(which most of us didn't use nowadays).
It doesn't have any line-in for me to input any other audio hardware which i can make use of the radio (as a speaker).
I kind of like it, so I decided to modify it make it useful.
My idea was to rectify the CD input into a line-in port, which most modern music players have. I'm also interested to hear others idea and opinion.
I have the manual of schematic circuit drawing of that particular radio player called PHC-ZW770L.
But I myself couldn't fully have the idea where should I edit it, as I only have little knowledge about audio. These are the following problem i'm facing:
- As commonly known, a stereo adapter have 3 wiring, which is ground, Left & Right. I'm thinking of connect these 3 wiring of another line in cable to take over CD's wiring.
In the circuit board, i only found/know it have a L&R-channel input, but i didn't found any words match of grounding purposes. ( the part consists of wiring such as "R.CH", "L.CH", "CD.5V(CD-H)", "CD.GND", "P.GND", "P.VDD(6.2V)"
- Is it possible to just disconnect the wiring for CD's and Tape' to save electricity(as in didn't use at all), or we need to edit a little bit to do so ? (like changing resistors as so on).
