Another update. I redid the RF alignment and it helped a bit but not much. The antenna trimmer did not weaken or peak the signal. I unplugged all walwarts in my shop and that helped a little more. But still not gone. I have gone over my work several times and found no problems. I checked voltages and they see close. Some higher and some lower. What I did notice was 12BA6 next to the 12BE6 had 12.9 vac on the filament and the 12BE6 had 11.8 vac. Also the pilot only has 4.4 vac. These readings were from input voltage of 111 vac. Should't they all read close to 12 vac? At this point everything has been changed except 3 resistor which measure pretty close. Maybe my problem is just plain bad reception and house electronic noise.
