Need advice for adding aux-in/line-in to Philips AE2160/00-A AM/MW/LW portable radio
I'm from Germany, so please excuse my grammar! :D
The reason why I'm opening up this new topic is, I didn't find any instructable or guide on how to add an aux-in/line-in to my simple mono AM/MW/LW radio Philips AE2160/00-A.
There's not much to find out about the technical specifications besides the standard product information:
• Analogue tuning
• Wave ranges FM 87.5 - 108 MHz
MW 525 - 1606.5 kHz
/04 LW 150 -255 kHz
• Ferroceptor for MW (and LW)
• Telescopic aerial for FM (and SW)
• Max. output power 300 mW RMS
• Tone control Music /News
• Loud speaker 100 mm
• Metal grill
• External supply
/00c, /04 230V
/05 240V AC
• Batteries 2 x 1.5V , type R20/D
• Headphone socket 3.5mm
• Material Polystyrene, metal grill
• Weight (g) 520
• Dimensions (mm) 210 W x 150H
Here's a link to a photo of the device:
I didn't even find schematics/circuit diagrams for this or a similar device. There are lots of tutorials on how to add such an input to a car radio or a boombox/stereo cassette player a.s.o., but not for a simple AM/MW/LW radio.
My questions are:
1.) Are there any similar hack projects here in the step-by-step or forum section?
2.) How do I find the right connector or place to solder a 2-way-switch between the sections (tuner, amp, speaker)?
After the hacking job, it should be possible to switch between normal radio listening mode and aux-in/line-in mode from an external mp3 player, notebook, a.s.o..
3.) Is there anything else to know for this project?
Yesterday I've opened up the case for the first time and looked over the circuit board and the connections.
I had no cam to take pictures, but I try to take some mobile phone cam pictures of the circuitry and parts at the next opportunity!
