Hammond PWDI13131 Johnson Viking 500 L302 10 HY 200 mA Choke

PWDI13131 is a choke for the Johnson Viking 500, position L302, cross-referenced to P/N 22.1264. It is part of Hammond's PWDAHL Series, the chokes and transformers catalogued directly from the Peter W. Dahl files of magnetics for amateur radio products, and is intended for Viking 500 owners and restorers.

The choke is rated 10 HY @ 200 mA DC with a 350 WVDC working voltage, a lower-voltage position than the L303 high-voltage choke in the same transmitter.

PWDI13131 is wound on an EI-112 x 1.5 core and listed as Style 2 on the series style sheet. The approximate weight is 4 lbs and the shipping weight is 4 lbs (1.81 kg). It is REACH compliant and RoHS compliant.

Hammond explains that PWDAHL units are usually built to order one at a time, and recommends confirming availability by phone or e-mail. The part carries UPC 623980284200 and UNSPSC 39121301.

Restorers servicing the complete Viking 500 supply can pair PWDI13131 with the L303 HV choke, PWDI13036, which is drawn from the same Peter W. Dahl files. Quoting P/N 22.1264 with the Hammond part number helps confirm the correct choke when checking availability.
