Lynx Head Phones

I had a problem with my Lynx head phones which I have solved, but I ran into something I had never seen before, often battery charger units have an LED to indicate they are working, but on this charger unit, all the charge current goes through the LED, the current is limited to 34ma RMS. These measurement were take with a Fluke 87.

My other purpose of this post is to share what I have found out, and that is how to supply power to them if you don't want the weight of the batteries on your head or want to listen to music while your using them.

In the 90s cordless phones of which I repaired many used the same technique, only charge current was a smidge higher and the led was shunted with a resistor as well.
