AJ 9200R Radio-Added a Line In Jack.

Postby darrenwgaransi+ » Fri Sep 27, 2019 3:48 pm

Hi Everyone,

I always wanted to add a line in jack to my AJ 9200R Radio. I went to the junkyard and purchased an extra one, along with the wiring harness so that I could experiment with it on the bench. I then went to a local thrift store and bought a 12 volt, 3 amp power supply that was originally intended for some type of gaming console.

I spent a significant amount of time poking around and studying the circuits and I think I came up with the best solution-I then modified my actual radio. Here's what I did:

1. Locate the 4 blue coupling capacitors on the front of the board, just to the right of the Dolby chip. They are polyester film types and they appear to be 470pf.
2. The first and last capacitor in the row couple the radio output to the preamplifier. One is for the left channel and one is for the right.
3. Unsolder the side of each cap that connected to the radio output.
4. Take a thin shielded stereo cable with conductors for left and right; solder each of the two conductors into the holes left behind from where the capacitor was lifted. These will be your radio out connections.
5. Take another think shielded stereo cable with conductors for left and right; solder each of the two conductors onto the ends of each capacitor that was lifted. These will be your line-in connections.
6. Connect the shields from both wires to the radio chassis.
7. Take both wires and thread them through the front of chassis and out to the right hand side where the faceplate screws on.
8. Drill a hole in the upper right hand side of the faceplate.
9. Solder the two stereo cables to a stereo switching 3.5 mm phone jack. There are 5 connections-L signal in, R signal in, L signal switched, R signal switched, and ground.
10. Put everything back together and reinstall the radio.

In operation, plugging in to the new jack, your sound source such as a smartphone, will disconnect the AM/FM tuner from the preamp, and feed in your sound source. That way, there is no bleed through from the tuner, tape player, or CD player. You will find that while you have your sound source plugged in you can still toggle between the CD changer and the cassette without having to unplug your sound source from the new jack. You only have to unplug from the jack to re-establish the tuner.

My smart phone sounds fantastic this way! The quality is way better than the previous configuration which was through a cassette adapter. I also like the fact that the cassette player doesn't have to spin unnecessarily any longer.

Excellent idea Darren - too bad you didn't take some pics though :( ..I've got a spare unit too and winter's coming (according to Game of Thrones) so sounds like a good project to take on ..BTW how did you get around the spare asking for a code? Did it have one?

Hi Larry,

I still have the spare apart, so I’ll take pictures of that, and of the actual unit in the car with the jack installed. A code was written in wax pen next to the faded label on the hood but it didn’t work. I unsoldered the bridged contacts on the bottom of the board which recorded the radio to 1324.

Had to re-read your post couple of times, very clever way with a phone jack selector. I always thought about doing similar thing but just using tape outputs and a bluetooth adapter connected to line-in but that would require fitting a 3PDT selector microswitch somewhere too(to get past the tape switch issue and to select source between tape and bluetooth) and at least one more button to actually switch bluetooth on and there isn't really much space anywhere to fit one on that radio. I suppose one could actually delete the tape entirely and change it to bluetooth by making the tape switch on all the time and fitting bluetooth adapter instead of tape drive but you'd still need a BT button somewhere.

Some pics or a simple schematics would definitely help :)

Well either load them into photoshop and resize them :D or email them to yourself, select medium size then upload the images from the email ..

I actually selected the small size and emailed them to myself. It didn't work. Is there anyone I can email them to so that they can be uploaded to this thread?

How big are they to begin with? (Large size) ...and how many?
