with that video of a home made tube going round these days...

(and it turns out that guy was someone i worked with back in the midwest hifi days 30 years ago)

I figured i would show a picture of a tube i made by hand in 1976 (at zenith)

Has a couple of bugs in it. (actually a bug and a butterfly)

Proving without a doubt that i was nuttier, longer than just about anyone.

(made from picture tube necks)

Yup, definitely crazy, but in a good way.

That's lovely

oooh, I call girl-dibs on any future nuttiness tubes you want to make with bugs and butterflies in them!

You posted the same image twice. Since there's a "tube2.jpg" on your site -- and it's related -- I'm going to assume you meant that and fix your post.

wow. do you still have the equipment for it?

and if you don't... are you willing to fabricate it?

Got to start watching those cut and paste's...

Actually with the glass shop at northwestern university shut down,

i have stashed one of the 3 glass lathes. So i do in fact have the

necessary stuff including bakeout ovens and turbo pump down systems

to actually build tubes. Even have a 50 year old RF generator suitable

for flashing the getters.

The nichrome wire and the rest of the stuff is easy except if i want to do

thoriated filaments or indirect cathodes. The cathode material is nasty.

Getting new getters probably not so easy either.

The bug and butterfly were cloisene'd enamel.
