Western Electric Type 218B INPUT Transformer, For Tube Amplifier
Item History & Price
You are bidding on a Western Electric type 218B InputTransformer. This is a nice vintage transformer with good windings. I was unable to find the specifications but this is the input transformer used in the 7A amplifier from the 1920s. The high side resistivity measures about 6170 ohms across terminals 3 and 5, and it is not quite centertapped at 3590 and 2580 ohms, with my Fluke meter. The low side measures about 1050 ohms, terminals 1 and 2. It was... used with 216A output tubes. It is in fairly acceptable condition with just some very slight corrosion, as seen in the photos. It measures roughly 2 1/8 by 1 3/4 inches in cross section, and is 3 1/8 inches tall. It is a quality transformer that should be great for use in your amplifier. Shipping weight is 1.5 pounds. Please see my other auctions for more interesting radio and audio items and tubes.
