OK, thanks for this info.
The article quoted said that blue/violet glow within
the plate structure was OK. So which is it?
OK or not OK?
Mine started out blue but has now changed
to violet and has always been within the gap
between filament and plate of the tube
(both sections).
Reverse current measures 0.00 on a 200 uA scale
with about -60 volts on the plates. So there do not
seem to be any free ions in there to conduct any
current.
