The PWDP13134 is a combined plate and filament power transformer for the Amp Supply LK-450 amplifier, designed for a single 3-500Z tube. It comes from the Peter W. Dahl design files and is aimed at amateur radio operators and service technicians repairing or rebuilding an LK-450.
The primary is 120/240 VAC, 60 Hz, single phase. Three secondaries are listed: S1, the plate winding, delivers 2080 VAC at 0.4 A ICAS; S2, the filament winding, is 5.5 VCT at 15 A CCS; and S3 provides 11 VAC at 2 A CCS. Note that S1 carries an ICAS rating while S2 and S3 are rated CCS.
The transformer uses an EI-175 x 2.5 in. core of 29GAM6 laminations and is built in style 4 of the series style sheet. Approximate weight is 17 lb, and the shipping weight is 17 lbs (7.71 kg). It is listed as REACH and RoHS compliant.
Because the PWDP13134 primary is listed for 60 Hz only, buyers outside North America should follow the series advice to choose 50/60 Hz parts for 50 Hz mains. Series units are usually built to order one at a time; confirm availability before ordering.
