This video covers the basics of the design and analysis of triodes using cathode feedback and fixed grid biasing arrangements. Examples of analysis and design problems using 12AX7, 12AU7 and 12AT7 dual triodes are presented. Experimental results are also reported to reinforce the theory that is presented.

EXCELLENT PRESENTATION!I WAS HAVING TERRIBLE TIME READING THOSE GRAPHS THOUGH,CALIBRATION GOOD BUT,GRAPH TO SMALL.

They’re hard to read even at full size. The best thing to do is print some out from the PDFs online and work along with the video. I am working on cleaning them up but it’s going to take a while.

Great lecture again! Quick question, with regard to Q point. What sort of basic requirements drive choosing a particular Q point for a vacuum tube type. Is it the application of the circuit, say a record pre-amp, or a headphone amp or guitar pre-amp, and/or operating requirements like efficiency, plate dissipation, available power supply, etc?

@@peterbulanyi1708 several factors. In most applications we want the Q-point centered on the AC load line for maximum unclipped output. In a guitar amp we might choose this location or a location that produces asymmetrical clipping. As long as the load line is within the SOA it’s all good. There are subtle things to consider too but I’ll get to that in a few videos.

Cool! Can't wait till you get to pentodes. Btw I have designed, analysed and built some interesting topologies with pentodes you might want to take a look.

Pentodes are on the menu!
