Hello coilers,
I know it is true that one shalt not touch the glass of a halogen bulb or
the vacuum will be compromised by the oils in the skin. Is this true in
general of vacuum tubes?

No and I don't think that's the reason for not touching the
envelope of those light bulbs. The explanation I've heard is that
any fingerprints or the like can carbonize and cause local heating
which is injurious. I don't think those things operate under high
vacuum conditions anyway. Anyone know?
