You are bidding on a NYTC type 27336 input transformer, probably for use in a tube type amplifier.  It is rated at 365 ohms to 33K ohms at 350WV.  The windings are good, measuring about 175 and 3000 ohms with my meter.  It appears to be in good useable condition.  It measures 7/8 inches in diameter, and is 1 2/8 inches tall, not counting the terminals or mounting bolts.  Shipping is $4 by first class mail in the US.  Please see my other auctions for more interesting radio and audio items, and tubes.
