SIlver body

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.

For more details, we would like to suggest you to refer to the official catalog of TAMURA audio transformers through TAMURA's web page below.

http://www.tamura-ss.co.jp/catalog/index.html
(NOTE: it can be seen with "pdf" file.)

On the web page, it is listed in the middle as CAT. No. "C-1005-10". At this point, if you find the word "AUDIO TRANSFORMERS" on its left side, please click on the word or on a small picture on the other side to see the catalog (392k in "pdf" file).

Also, if you need some more useful information (but written in Japanese) about TAMURA transformers like how to connect terminals, characteristic figures, etc., please click on the word "Audio Trans Technical Report" just below. Thank you.
