Drake L4B Direct Replacement 6-Terminal Transformer

The PWDP13241 is a direct replacement transformer for the Drake L4B, supplied with a 6-terminal primary; its part page lists it as "DRAKE L4B-6". It is part of the PWDAHL series of Peter W Dahl Transformers, magnetics for amateur radio products, and is intended for owners maintaining or restoring a Drake L4B.

The primary is 120/240 VAC, 60 Hz, single phase with hi-lo taps. The single secondary, S1, is rated 1065/780 VAC at 0.81 A on a CCS basis.

Construction is a large EI-212 x 3 lamination core in Style 2 on the transformer style sheet. Approximate weight is 29 lbs, and the shipping weight is 29 lbs (13.15 kg). The PWDP13241 is marked RoHS and REACH compliant, and is identified by UPC 623980046976 and UNSPSC 39121301.

The dual-voltage S1 secondary is rated 1065/780 VAC at 0.81 A CCS, and the hi-lo taps on the 6-terminal primary are what the ordering table describes as making this a direct replacement for the Drake L4B.

This is a 60 Hz design; the series advises buyers outside North America who need 50 Hz to select a part marked 50/60 Hz. PWDAHL transformers are usually built to order one at a time, so check availability before ordering.
