All the old farts ... I would like to tap into your knowledge on how to build a vacuum tube.

I built my very first valve amp - the famed Mullard 5-10 - from this very book (of which I have the original) when I was in Standard 6. This is the Bible of valve audio circuit design, enjoy!

OK, I will be following with interest, might even be tempted to do the same!

Watched a few Tube videos and it basically is a simple manual process. The main tooling is also quite simple.
Main thing is to know your chemistry and metallurgy. No issues with this.
Glassblowing is about the most difficult portion of the manufacturing process.
Then the design of the emmiter(s) and collector(s) is one issue that lays barren before me. Surely there is a ton of knowledge on this in this community?

A Japanese gentleman by the name of Toshi Kurashima shows us how it is done!

Been reading a bit ...OK, that is besides the Louis L'Amour books!
There are two books that I must get hold of it seems:
- Vacuum Tubes by Karl Spangenberg and
- 1962 RCA Vacuum Tube Manual
Let me get hold of these and see what vintage treasures are hidden between their covers!

A mate of mine is a porcelain expert so he can make the stands into which the tubes fit. No issues there for him.
Glass blower? I will have to ask around here in my valley. There used to be world renowned glass blowster (is this the correct feminine form?) in town.

Question ... if I design and make a vacuum tube valve, which model would you like to see?
My only criteria is that is must normally retail for enough to generate a profit when made in small quantities.

People should be able to build a respectable amplifier using something like ECL82 or ECL86 type valves, although this might be a bit complex to manufacture. A combined Triode-Pentode.
An octal-based valve would probably look better and easier to make but that would rule out a triode-pentode in one envelope.

Any model number you would recommend @Family_Dog ?

Not enough pins on an octal base for a triode-pentode unfortunately

This is simply respect ... The only thing I need is the castle!
