Hammond PWDP13074 4000 VCT Plate Transformer for Globe King 500B

The PWDP13074 is a Peter W. Dahl plate transformer for the Globe King 500B transmitter. The ordering table lists it for a 1800 VDC @ 400 MA CCS supply using a full-wave bridge (FWB) with choke input, making it a fit for restorers rebuilding the 500B's high-voltage supply.

Its secondary is rated 4000 VCT @ 400 MA ICAS and is marked FWCT (full-wave center tap). The primary is 115 VAC 60 Hz single phase.

The transformer uses an EI-175 X 5 lamination core in Style 5 and has an approximate weight of 31 lbs. A modified version for a 120/240 VAC primary is listed separately as PWDP13108.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980186146. Shipping weight is 31 lbs (14.06 kg).

The PWDP13074 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.
