Hammond PWDP13091 1080 VRMS Power Transformer for National NCL-2000

The PWDP13091 is a Peter W. Dahl power transformer for the National NCL-2000 amplifier, providing its plate and screen voltages. It is for NCL-2000 owners and technicians replacing the amplifier's high-voltage transformer.

Two secondaries are provided: S1 at 1080 VRMS @ 0.91 AMPS CCS for the plate supply and S2 at 450 VRMS @ 0.070 AMPS CCS for the screen. The primary is 117/234 VAC with HI-LO taps, rated 60 Hz single phase.

It is wound on an EI-175 X 4 lamination core in Style 2 and weighs approximately 25 lbs.

The part is listed as RoHS compliant and REACH compliant, with UNSPSC 39121301 and UPC 623980143033. Shipping weight is 25 lbs (11.34 kg).

The PWDP13091 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.
