an old diy project

[kevin gilmore]

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.

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?

[kevin gilmore]

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.
