From: fred MC Kenzie Subject: DX440 Modification The little piece of plastic which covered the supposed position of the jack, I found no jack at all. I guess I have to hardwire one. So is there any mod plan of doing this ? I'd like to use DX440 as a tuner in a stereo system. Thanks in advance Ming. There is a place for the rec out connector, just inside the hole covered by the little piece of plastic. Order a cassette jack for the Radio Shack Color Computer, from Radio Shack parts department. You may have other sources for this PCB mounted, 5 pin DIN connector, since it is fairly common. Before attempting to mount the connector, you may have to clean any excess solder out of the holes on the PCB. It's a tight fit, so be sure the connector is seated all the way. If you're successful, it will look like a factory job when you're through ! Of the 5 pins, the center one is signal ground. Two pins on one side of center, are connected via resistors to ground. The two pins on the other side go to low level, left and right stereo signals. They are fed from voltage-dividing resistors, so short circuiting them will not hurt anything. The signal level is just right for many tape recorder microphone inputs, and is not affected by the DX440 volume control setting. Fred MC Kenzie |
