The 'late Ziggy Peacock'? When did that happen and why didn't anyone tell me?? And how did he send that e-mail. Eerie.

Cliff et al.,
I am a bit late with the report of my experience, nevertheless:
Years ago I built our wonderful Ruben's tube
following the competent directions of the grand
master of physical ceremonies, the late Zigmund
Peacock. At first I was very scared when firing
up that long, fat tube full of propane gas. It
was due to much feedback on tap-l that I calmed
down and wnet ahead to fire it up for the very
first time. All was good and it worked amazingly
well ever since. In fact I got very much used to
it by now and have in fact shown the Ruben's tube
à la Ziggy seven times last Saturday along with
some other highlight demonstrations as a part of
public performance in our big and very crowded
auditorium. For this I actually made a LabVIEW
program that plays a little song I composed by
using several of the necessary frequencies and
amplitudes which are defined by our tube. The
Ruben's tube usually triggered a special applause
when playing the song.
It's the way I like to go about; control my real
world demonstrations with self made software that
does exactly what I want and how I want it.
In your case of course the normal precautions
should be taken but you should not worry too much.
