Re: 82104A card reader magnetic head Message #6 Posted by Randy on 10 Aug 2005, 12:09 a.m., in response to message #5 by Carlos
3 each 82104 = 3 heads x 2 windings each = 6 coils. Just as you asked. All the same resistance since my Fluke doesn't have an impedance setting :^)
I have only seen one bad head ever, on a 97. It was open on one winding. I don't know if a 75 ohm winding would cause a problem. It's much more common for the card detect switches to be the issue as they are easily bent while handling.
