To a degree, I have to agree with Mike.
Have you rewound the oscillator coil? If not, I would try baking the coil for 30 minutes at no more than 200 degrees Fahrenheit. That should remove moisture from the coil form and the radio should perform better as a result.
If the problem persists after baking the coil, then you could consider a 2A7 mod.
The autodyne circuit was a poor design to begin with, and it would bite Philco in the behind, especially with troubles with the 19 and 89 later on.
