Any obvious signs why your F9020 is dead ? If there is an inherent manufacturing problem with this tube, perhaps due to it's unconventional shape, it could explain why they are so rare. There were probably billions of round vacuum tubes produced so I'm sure all the obscure problems were solved for that style.
Unless you have a pile of dead ones, I wouldn't risk trying to re-gas yours. Even as a paperweight it's a treasure. I have this nagging fear (nightmare ?) that one day my tubes start dying-off, even the ones I stockpiled as replacements. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
