[Thursday] Making Vacuum Tubes

[Chris Prata]

Hi All,

I think eventually we could use our upcoming workshop to make simple vacuum tubes. I have watched a number of videos and it's really not that hard. With Randy's machine and manufacture expertise we have a resource for jigs and whatnot.  😉

So, in my humble opinion I think that down the road this could be fun and would certainly exhibit a process that is a direct match for our Wireless offerings. A quick search for "radio museum making vacuum tube" didnt turn up anything.

Here is a video (one of many) which I found randomly on the you tubes Making vacuum Tube:

Also stumbled upon this museum. I dont recall it being shared to list so here it is. Nice one page summary of the development of early receivers from crystal through superhet.

Turning the station tuning dial also tunes a internal radio frequency signal. The internal signal is varied so that, when it is combined with the tuned station signal, it always produces a new signal with a specific frequency, called the intermediate frequency.
