What I think is more likely is that the wire is stressing the phenolic board and flyback.
The CRT isn't quite as bright as I expected considering it tests like new and is aluminized. Perhaps that's because the HV is only 12kV for the original 17AP4 while a 17BP4 typically sees 14kV.

Your CRT is aluminized? I don't think you should need an ion trap, then.
