The caps inside the AM IF transformers would be hard to measure as they are across the windings, you would have to remove them to measure, which means taking the transformers out, and apart. I'm pretty sure that one or more of tie mica caps in those transformers might be open if adjusting the slugs doesn't do anything to the gain. I have an older AM/FM radio that has the opposite problem, the AM side is fine, but the FM is deaf, only picks up the two strong local stations, and rather weakly, the tubes are fine, tested those, it could be the electrolytic for the ratio detector but maybe not, so on the shelf it sits.
