Hammond PWDP13105 750-0-750 VAC Power Transformer for Heath DX-35/40

The PWDP13105 is a Peter W. Dahl power transformer for the Heath DX-35 and DX-40 transmitters. It serves Heathkit restorers replacing the transmitter's original power transformer.

It supplies four secondaries:

• S1: 750-0-750 VAC @ 150 MA ICAS (FWCT)
• S2: 6.3 VAC @ 3.25A CCS
• S3: 5.0 VAC @ 3A CCS
• S4: 6.3 VAC @ 0.65A CCS

The primary is 117 VAC 60 Hz single phase. It is wound on an EI-125 X 1.75 29GAM6 lamination core in Style 5 and weighs approximately 6 lbs.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980930473. Shipping weight is 6 lbs (2.72 kg).

The PWDP13105 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.
