Power transformer qquestion - 45philcodon - 03-29-2024

I have just begun restoring a Model 38-620. The power transformer has obviously over heated in the past: wax leaking out of the transformer and splattered around the local area. All windings ohm out correctly.

Is this transformer safe for future use? In any case I intend to add an in-line 3/4 Amp fuse.

Thank you

Don

Pull out the rectifier tube and run the set for 5 or 10 mins. If the transformer get warm or hot it's probably has shorted turns. Measure the HV ac from the each end to the centertap. Voltage should be within 10v or less.
