Hammond PWDF13229 LK-500 Amp 5.5 VCT 30A Filament Transformer

PWDF13229 is the Amp Supply #LK-500F-1 filament transformer for the LK-500 amplifier. It is part of Hammond's PWDAHL Series, the transformers and chokes catalogued directly from the Peter W. Dahl files of magnetics for amateur radio products, and is intended for LK-500 owners and technicians.

The secondary is listed in the ordering table as "0S1) 5.5 VCT @ 30A CCS", a 5.5 volt center-tapped winding rated 30A CCS. The primary is 115/230 VAC, 60 Hz, single phase. As a 60 Hz part, it falls under the series advice that buyers needing 50 Hz should look for a part marked 50/60 Hz.

The transformer is wound on an EI-150 x 1.5 core and listed as Style 4 on the series style sheet. The approximate weight is 8 lbs.

PWDAHL Series transformers are usually built to order one at a time, and many of the designs are decades old. Hammond advises confirming availability by phone or e-mail before ordering PWDF13229, especially if an amplifier repair is waiting on the part.

The ordering table groups this part with the other Amp Supply LK-series transformers in the PWDAHL listing, so quote both the Amp Supply number (#LK-500F-1) and the Hammond part number PWDF13229 when requesting it.
