I was never a fan of increasing the voltage on a CRT filament, even temporally.
I always thought that that was a good result for CRT manufacturers, parts sellers, and techs, but not consumers.
Power is proportional to the square of the voltage... and power here is heat.
So on a filament some hours on it, that's going to do some irreversible damage.
It's not going to do the cathode any good either.
No one makes these CRTs any more.
That's a good reason... IMO... not to abuse them... even innocently.
It's not so easy to get a replacement... except, and perhaps, from a parts mule.
'Some display' wagered against a 'potentially better display' is... IMO... much better than 'no display'
