Easy to check for interference. Take it outside and try it. Plug it into a different circuit, etc. If that doesn't fix it, make sure the tuning cap is clean. Dust between the plates can cause static. Resistors? I always check them when I am recapping. If you didn't, you can be sure that at least some of them have drifted in 73 years. I don't know if that would cause static though...
