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
