PWDF13103 is an exact replacement filament transformer for the B&W PT2500A. It is catalogued in Hammond's PWDAHL Series, which reproduces transformer and choke designs directly from the Peter W. Dahl files for amateur radio products, and is intended for owners and technicians restoring this amplifier.
Three secondaries are provided:
- S1: 90 VAC @ 60 mA CCS
- S2: 6.3 VAC @ 1A CCS
- S3: 5.2 VCT @ 30A CCS
The primary is listed as 15/230 VAC, 60 Hz, single phase. As a 60 Hz part, it falls under the series advice that buyers who need 50 Hz should look for a part marked 50/60 Hz.
PWDF13103 is wound on an EI-125 x 2" 29GAM6X core and listed as Style 2 on the series style sheet. Approximate weight is 7 lbs, with a shipping weight of 7 lbs (3.18 kg). It is REACH compliant and RoHS compliant. PWDAHL units are usually built to order one at a time, so Hammond advises confirming availability by phone or e-mail. Identifiers are UPC 623980143026 and UNSPSC 39121301.
Because the ordering table describes PWDF13103 as an exact replacement, the three secondary ratings above are the values to check against the original PT2500A filament transformer before installation.
