If, when you get all caps replaced, tubes checked, and out of value resistors changed, the radio still has issues (such as a staticy sound or the volume not being constant), suspect the IF transformers. This set uses the small ones that are prone to the silver mica corrosion.

The cure is to carefully take them apart. Then remove the old caps and replace them with new ones of 100pf or so. It is a tedious process, but the radio will play fine once this is finished.
