This section starts off with a brief history of the vacuum tube development and some of the early pioneers who help shape and develop the vacuum tube Industry. Introduction to Vacuum Tube Electron flow and the Vacuum Tube Elements , Cathode & Plate. An Introduction to Vacuum Tube Heating Elements (Filaments)
Continued Discussion On Vacuum Tube Diode Principles.
The Following is Covered in this Section.
Diode Theory and Electron Emission
Space Charge
Cathode Emission Rate
Cathode Emission Rate Vs Temperature
Vacuum Tube Plate Resistance, Both AC & DC Resistance
Triode Vacuum Tube(s) are Explained in this Section. The Triode Control Grid is explained along with the relationship between the Grid Control Voltage and the Triode Plate Current. The Plate resistance of a Triode is Explored further. Several Triode Family of Curves are also Discussed in this Section.
Continuing Discussion on the The Vacuum Tube properties of DC Plate Resistance , AC Plate Resistance , Conductance & MU (Amplification Factor).
In this lecture Al explains how to create a load line using a Triode Vacuum Tube. Topics covered ,How to find the two end poits of a Vacuum Tube Load Line. How to find the best Biasing and/or Q point on s Vacuum Tube Load Line. How to find the output Voltage level of an Output Signal. How to determine the Gain of an a Vacuum Tube Stage.
Al Introduces the Screen Grid and the advantages of it's development in to the Vacuum Tube Technology .
The Suppressor Grid is added to the Vacuum Tube, this is the 5th Element added. Al explains the reasoning behind adding a Suppressor Grid for the Vacuum Tube development. Al Also explains the Tube Curves associated with the development with of the Pentode Vacuum Tube.
A short Video On Vacuum Tube Bases
Al Explains The Three Main Amplification Classifications, Class A , Class B & Class C. Type of Vacuum Tube Biasing.
Al goes into a deeper Discussion on Vacuum Tube Load Lines.
Al takes and demonstrates for the Student(s) some common Vacuum tube Properties .
Current flow in the Vacuum Tube Diode.
the function of the Plate & Cathode
Function of the Vacuum Tube filament (Heater)
Al continues with Vacuum Tube Demonstration Lab(s)
This Course starts off with Vacuum tube basics. Starts off with the Introduction of Vacuum tube Elements (i.e. Plate , Cathode) , Course also covers Space charge, Electron flow in a Vacuum tube.
The first part of the course covers Diode vacuum tube(s), explains and shows the Voltage and Current Curves associated with Diode vacuum Tubes. The course then expands with explanation with Triodes , where the control Grid is added. The Control Grid is the explained as ea Vacuum tube Element is Introduced. Tetrode is then Explained next with the addition of the screen grid. Ending Up with the Pentode where the Suppersor Grid is added and Explained.
In all of Tube Categories we cove Rp (Ac Plate Resistance) & RP (Dc plate Resistance) and other Vacuum Tube properties (i.e trans-conductance ,mu ) and there relationships between them.
We also Have a mini course with in this course that covers the application and usage of Vacuum tube triod lines.
The Course then ends with follow along labs if the student wishes to do so.
Explains the different components of a Vacuum tube and their Function(s)
o Heater Vacuum Tube Element.
o Cathode Vacuum Tube Element.
o Anode Vacuum Tube Element.
o Plate Vacuum Tube Element.
o Grids (Control Grid, Scree n etc.)
Al then Explains the Vacuum Tube Load Line, How to Bias a Vacuum Tube.The Operation of the Vacuum tube.
