The 630 I rehabbed was playing pretty good. Now it plays well on strong stations but a lot of static on weaker stations and while tuning between them, I probed around with a plastic alignment tool and notice that when I put some pressure on the 2nd IF transformer the Volume decreases and the static lessens. Is this what is known as Silver Mica disease? The schematic does not document what size capacitors I have in the can. The transformer windings ohm out at 12 ohms. The transformer is a 32-1647. Any idea what size capacitors are in the can? If I ground out the antenna the noise is still there controlled with the volume. Am I correct assuming that the noise then is being generated inside the radio? On strong local stations it is still there but not as pronounced.
