I've also had those symptoms once from a bad IF transformer. In that case, the capacitor in the can was fine but the insulation had evidently broken down in a weird way. I'm not sure what caused it, because it was magnet wire, but if you measured it hot it measured very different than it did cold. I expect some slight shift, but what it had was way too much.
If it turns out this has happened to your radio too and if you can't find a replacement, check this page:
