keep the set in a air conditioned eviroment (low humidity), make sure the HV is properly set, both the anode voltage and the eff coil for min current. Make sure the regulation is working properly, use a variac or a bucking transformer and see how low you can go and still get normal operation. I generally use 105-110vac which seems to work fine. If you do all of the above I doubt the fly will be a problem.
