EI-14 Audio Transformer, 5 pcs/Pack, 1K:8 Ohm Impedance, Isolation Output XFMR

I needed them to make a laser communicator for a class project and they worked perfectly for this application. I can't speak for the long term reliability as I did not use them for long, but out of the box they worked perfectly for me.
