When the Chinese were making 3-500Z tubes with regular glass 
and holes were sucking in the sides, Rich concluded it was a 
VHF parasitic that couldn't be seen or measured. This VHF 
oscillation supposedly caused dielectric heating of glass at 
VHF.

Paul Hrivnak of Viewstar, Palstar, Vectronics fame was 
building a single 3-500 amp using that particular Chinese 
tube. He changed to nichrome suppressors and tubes kept 
right on failing.
