When you adjust the IF compensators on top of the aluminum cans, be sure to adjust them in the order suggested by the schematic. Usually you adjust the 2nd IF compensators first, then the 1st IF compensators. Once you finish all four, you'll probably need to do it again at least once. Be sure to do them in the same order.
Your radio has adjustments for both the primary and secondary compensators. The order is: 37a, 37, 31a, 31.
You didn't say if you had a schematic. There is a free schematic in pdf format here:

The reproduction quality is not very good. You can buy a better quality reproduction of the original Philco service data for a reasonable price from Chuck Schwark at his web site:

On the free schematic, top of page 3, there is a diagram showing where each of the compensators is.
