Hammond PWDP13034 Heath SB-220 Factory-Original Power Transformer

PWDP13034 is the factory-original style power transformer for the Heath SB-220, listed as a Heath HL-2200 power transformer replacement for the SB-220, SB-221 and HL-220. It suits amateur radio operators and repair technicians who want to replace the power transformer in one of these units.

The primary is rated 117/234 VAC, 60 Hz, with HI-LO taps, allowing the amplifier to be set up for either mains voltage and a HI or LO tap setting. The secondary delivers 860/1171 VAC at 0.7 A CCS.

The transformer uses an EI core and is listed as Style 2 on the series transformer style sheet. Approximate weight is 23 lbs, with a shipping weight of 23 lbs (10.43 kg).

For buyers comparing options, the same series also lists an extra heavy-duty 7 mil C-core version rated 1.3 A CCS (PWDP13026), which requires chassis modification; PWDP13034 is the EI-core unit at the 0.7 A CCS rating. The primary is listed for 60 Hz only, so buyers outside North America should verify their mains frequency.

PWDP13034 is REACH and RoHS compliant, UPC 623980240213. Peter W. Dahl designs are usually built to order, so confirm availability by phone or e-mail.
