If you are getting -8 volts on the grid when the radio is tuned to a strong station and the eye is not closing, suspect the 1 meg resistor.
Looks like you only have 2 very strong stations:

Actually there's about 5 or 6 but 2 of them are stations for the Hispanic community and are in Spanish only, the other one you missed which is AM 960 WSBT which is the local CBS Affiliate's Radio Station, which is News Talk format and has been ever since it went on the air back in the 1940s, there are some others as well that I can get in fairly strong on my Radio like WOWO AM 1190 out of Ft. Wayne (they are a 50kW station that can be heard all across the the country at night), and then then WDND AM 1620 which is a top 40 Hits station, most any AM stations from around the Elkhart, Goshen, South Bend area can be picked up pretty easily on most of my old AM Radios, Also some Ft. Wayne Stations as well.
I'm guessing that the radio may or may not be in need of a realignment because I never touched that part of the radio, all I did was recap the radio and replaced the original tuning eye tube socket with a more modern one, and that was it. I did notice that when the tuner is tuned closer to the bottom of the tuner range the tuner gets really scratchy and noisy almost like the sound a volume or tone control makes when it has dirty contacts.
