Flawed IF Transformer in an AA5

[Winky Dink]

I’m redoing some of my early projects, starting with this Farnsworth AA5. Below is the 2nd IF transformer.



I’m guessing that the discrepancy in resistance is due to oxidation under the circled, light-colored area. The radio had been working with a ripple in the audio, and I haven’t yet done any realignment.

I’m going ahead with the re-restoration, but I’d like to know if I should anticipate any problems due to the flawed IF transformer.

I would greatly appreciate your advice.
