[Amps] Glass melting, f, and D-factor

[R L Measures]

It was previously stated by another denizen that the glass in early  
Chinese 3-500Zs was melting on the sides, however, according to my  
notes from Rus Healy, in this case, the glass reportedly softened on  
the top in an area a couple of cm from the anode stem, a small bubble  
formed, began expanding inward from atmospheric pressure, and popped.
