Hammond PWDP13071 6000 VCT Plate Transformer for Hallicrafters HT-33B

The PWDP13071 is a Peter W. Dahl plate replacement transformer for the Hallicrafters HT-33B linear amplifier, listed for a 2700 VDC plate supply for the PL-172. It suits amateur radio restorers and technicians rebuilding the high-voltage supply in this classic amplifier.

The single high-voltage secondary is rated 6000 VCT @ 0.350A CCS and is intended for a full-wave center-tap (FWCT) rectifier with LC filtering, per the ordering table. The primary is 120 VAC 60 Hz single phase, so it is specified for 60 Hz service only.

It is built on an EI-212 X 4.625 lamination core in Style 4 and weighs approximately 43 lbs, which makes it one of the heavier E-I units in this listing.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980186054. Shipping weight is 43 lbs (19.50 kg).

The PWDP13071 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.
