I would get a good NOS 3a3 anyway.

It sounds like the HV regulation may not be working properly. I would check the shunt tube cathode just to be sure. It also could be that you are just over driving the CRT trying to make it too bright. I am not going to try and explain checking the shunt, you can either read the sams or have someone else explain it.
