Hammond PWDP13210 Drake 1A Receiver Replacement Power Transformer

The PWDP13210 is a power transformer built for the R.L. Drake Model 1A receiver, drawn from the Peter W. Dahl design files that make up the PWDAHL series of magnetics for amateur radio products. It is aimed at radio restorers and hams who need a transformer matched to the original Drake 1A electrical requirements.

Electrically, the unit takes a 115 VAC, 60 Hz single-phase primary. It supplies two secondaries: S1 is a 525 VCT winding rated 50 mA CCS, and S2 is a 12.6 VAC winding rated 2 A CCS.

The transformer is wound on an EI-100 x 1.25 29GM6X lamination core and is listed as Style 2 on the Hammond transformer style sheet. Approximate weight is 3 lbs, and the shipping weight is 3 lbs (1.36 kg). The part is marked RoHS and REACH compliant.

Note that the primary is listed for 60 Hz operation only. The series notes that most Dahl parts are 60 Hz designs and that buyers outside North America who need 50 Hz should choose a part marked 50/60 Hz. PWDAHL units are usually built to order one at a time, so it is best to confirm availability before planning a restoration around the PWDP13210.
