It uses an EI-125 X 1.25" 29GM6 lamination core in Style 5 and weighs approximately 4 lbs.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980930497. Shipping weight is 4 lbs (1.81 kg).

The PWDP13114 is listed in the PWDAHL Series of transformers and chokes taken directly from the Peter W. Dahl files, a range described as magnetics for amateur radio products. These transformers are usually built to order one at a time, and because many of the designs are decades old it is always best to confirm availability by phone or e-mail before planning a repair around it. Units that have already been built are shown with Hammond part numbers, as this one is, and stock units can usually be shipped the next business day.
