This is a video with two objectives: One is to measure the transformers with a vintage General Radio Z-Y impedance bridge and compare the data to a new Mastech LCR meter. Second is to get a feeling as to how far the secondary impedance can vary from the published value without having the reflected primary impedance adversely affected.
