Need Help with Tetrode Sources.

[Patrick]

I'd like to study some vacuum tube circuits and there uses. So far when I do a google search I'm finding music amp tube sites and similar. Is there a better pdf or website source that focuses on the circuit theory and preferable physical characteristics of vacuum tubes? The tetrode type is of particular importance, I'm currently studying the 4CW1500,000E type by Eimac, a 150 kW continuous and 4 MW pulsed tube type operating in class AB. It weighs 47 lbs, and is water cooled, I have its datasheet and am currently reviewing it.

Any help would be appreciated.

EDIT: did find this which is sort of what Im looking for: https://www.physics-and-radio-electronics.com/electronic-devices-and-circuits/vacuum-tubes/vacuumtetrode.html

I have about 20 textbooks on vacuum tube design as PDF files. Most were published in the 1950s. I don't know if those copyrights still apply. If the administrator allows it I could post some of those if you want. Ask the administrator if its allowed.

The rules say its not allowed...

There are a lot of good ones here: http://www.tubebooks.org/technical_books_online.htm

If it can adhere to be free of copyright, due to age or not renewed, it can be uploaded on HVF, its a fairly long read , http://onlinebooks.library.upenn.edu/renewals.html

This looks like just what I wanted Anders Mikkelsen, thanks !

It does look like we operate in grounded cathode amplifier mode. We are effectively a triode but using the tetrode screen-grid as a hard on-off control and stray capacitance suppressor. So essentially we are using the tetrode as a triode.
I am looking for a simplified schematic of how a single amplifier cathode-grounded AB amplifier works. I'm not all that familiar with tubes.

Hey, I have started building triode tubes. The problem is I have no much information about the physical part. I mean, size of the filament, the plate, separations...

Any information will be well received!
