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.
