“Clip: [Restoration] 100 Year old Earphones Perfect DIY”

I restore these 100 year old earphones so that they work with modern equipment. These earphones are most likely around 100 years old as the patents were filed in 1923. I was really excited to see if I could get these headphones working again. This was my first attempt at vintage electronics, so I tried to stay away from the more sensitive electrical components.
