Description
WELCH ALLYN 74710 OTOSCOPE/OPHTHALMOSCOPE TRANSFORMER (TESTED). This transformer is in good working order. We checked the output voltages and tested with a working otoscope head. All you need are the two 3.5V Welch Allyn heads of your choice and you are good to go.
Our Biomedical Engineering Department checked them with a working head and it worked as per design. Both handles receive the proper voltage, the intensity is adjustable and the micro switches work as they are supposed to.
Look at the image of the back of these transformers and you will note that they are easily hanged on your wall. All you need are a couple of screws on the wall and these transformers slip right on.
