Hammond PWDP13109 1200 VCT Power Transformer for Heath DX-20

The PWDP13109 is a Peter W. Dahl main power transformer for the Heath DX-20 transmitter. It is intended for Heathkit restorers replacing the DX-20's original transformer.

It supplies three secondaries: S1 at 1200 VCT @ 120 MA CCS, S2 at 6.3 VAC @ 2A CCS and S3 at 5.0 VAC @ 3A CCS. The primary is 117 VAC 60 Hz single phase.

The unit is built on an EI-125 X 1.75 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 623980930442. Shipping weight is 6 lbs (2.72 kg).

The PWDP13109 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.
