In Reply to: Filament Failure! posted by gusser on March 24, 2015 at 10:08:42:
at the opposite end of the scale I once tested a 845 filament (on an otherwise dud tube) to destruction. 50V on a 10V filament for an hour did not break it!
I have amps rated at 220V-230V AC input running various tubes with my mains varying from 230-260V and have never had a single filament failure. Admittedly, these days I always use inrush current limiters.
FWIW, I've run Svetlana KT88 filaments happily at 6.8V.
