I am restoring a 1947 Hallicrafters SX 42. I had been searching for the power transformer winding resistances with no results. The receiver is functional and the transformer is working fine. I am posting what I measured for resistances from this known working unit. All tubes and lamps were removed for these measurements.
Primary (120v): 3 Ω
5 volt secondary: 0.1 Ω
6.3 volt secondary: 0.2 ohms
High voltage to Center Tap #1 54 Ω
High Voltage to Center Tap #2: 58 Ω
