Western Electric Type 7A Auto Transformer, For Tube Audio, Good
Item History & Price
You are bidding on a Western Electric type 7A AUTO Transformer. This is a desirable transformer that was used in Western Electric audio equipment. The specifications indicate the ratio is 500:16 ohms. The high side DC resistance is 12 ohms, and the inductance is 9 Hy. Terminals 3 to 12 provide 2 DB steps between terminals. It is in fairly nice condition, but shows some slight corrosion on the sides. There is a Western Electric decal on one side which... is complete, but it is dark and hard to read. The transformer measures roughly 4 1/4 by 3 5/8 inches at the base, and is 4 1/8 inches tall, not counting the terminals. It is a quality desirable transformer which is seldom available. It should be great for use in your tube audio project. Shipping weight is 4.5 pounds. Please see my other auctions for more interesting radio and audio items, and tubes.
