Westinghouse WR-258 Power Transformer Replacement
#3

MrFixr55,

Thanks for the detailed reply. I conducted the dim bulb test today on the transformer which I had already pulled from the radio. According to my measurements, the high voltage secondary was only outputting 273 volts, with each leg unevenly split between 52v and 220v. The bulb glow remained fairly dim, but the transformer heated up pretty quickly (no smoke, sparks, etc.). I'm assuming the secondary is shorted somewhere.

I'll start scrounging for a replacement. The Hammond 270CAX will work, but the cost is higher and it doesn't lay flat like the original.

Already planned to add a fuse. Hadn't considered adding the diodes, but something to think about.

Thanks again.
