Interstage transformers

Interstage transformers, B-5000 and B-6000 series

B-5000 and B-6000 have same character without the exterior's color and the quality of the material.
B-5000 series is dark green color and made of Iron.
B-6000 series is potted in a silver-colored aluminum alloy enclosure. This series seems to be weak in the midrange compared to the B-5000 series.
