You might want to see if the unblanking pulses are doing what they're supposed to.? (or blanking pulses).? In some older scopes, there are diodes that have gone bad.? Do be careful, since they may run the cathode and grid at elevated voltages (like 2KV).
Grid - cathode voltage *should* change with the intensity settings.?? Hmmm......

Interesting that you mention intensity. The intensity adjustment does nothing. I am troubleshooting that now.
