You are bidding on a pair of Western Electric type AR 91 transformers, which were removed from a piece of tube type Western Electric equipment. The have the close date codes, 12V61 and 4V62. They appear to be good, and I see in a similar listing that these are rated at .013 MFD. They have a “+” mark, so they could be electrolytic. They measure about 2 1/8 inches tall and 1 13/16 by 1 1/16 inches in cross section, not counting the taps or mounting tabs. Someone else's listing says these are .013 MFD. They should be useful for someone for their tube amplifier project. Shipping weight is 11 ounces. Please see my other auctions for more interesting tubes and radio and audio items!
