I have some nos in box euro globe 45's with poisoned filaments. I wish I could find somebody I could trust enough to rejuvenate those. I plan to build an amp and try bake them for a day then run them in the amp in the hope they will come good.It does my head in that such tubes with new filaments cant work. Perhaps a current source on the filament might up the voltage until the filament resistance reduces.
