Hammond PWDI13230 Heath HA-10 Swinging Choke Replacement

The PWDI13230 is a swinging choke listed as the replacement for the Heath HA-10, drawn from the Peter W. Dahl files that make up the PWDAHL Series of magnetics for amateur radio products. It is intended for radio amateurs, vintage equipment restorers and repair technicians who need to replace the original choke in a Heath HA-10 with a unit built from the documented Dahl design.

The manufacturer's part page lists this choke with a shipping weight of 13 lbs (5.90 kg). It is marked REACH compliant and RoHS compliant, and carries UPC 623980398044 with UNSPSC classification 39121301. Detailed winding ratings, core size and mounting style are not published on the part page for PWDI13230, so buyers should confirm the electrical details of their HA-10 application with the manufacturer before ordering.

Transformers and chokes in this series are usually built to order one at a time. Units that have already been built are shown with Hammond part numbers, which is the case for PWDI13230. Because many of the Dahl designs are decades old, the series recommends confirming availability by phone or e-mail. Stock units can usually be shipped next business day.

When ordering from outside North America, note the series guidance: most parts in the Dahl listing are only listed for 60 Hz usage, and a part must say 50/60 Hz if 50 Hz operation is needed. The part page for this choke does not state a supply frequency, so check with the manufacturer if your station runs on 50 Hz mains.
