Hello,
I am designing a tube amplifier for headphones and am stuck trying to design a cathode follower. I am not looking for any tips or rules of thumb. The output of my amp is the cathode of a double triode and i used both a resistor network to ground and a 220 uF cap off of the cathode for the output (OTL cathode follower). My professor told me I should look into using a current source instead of the resistor network, but my electronics knowledge is spotty and I am not sure how to implement this. I have looked around but haven't been too successful.
So my question is that given that I'm using a cathode follower from an E182CC double triode and no output transformer, what direction would you guys point me in? where do you recommend I look for information (I know about the obvious TubeCAD, Jones' books, DIYforums)? what circuitry would you recommend? etc. I am open to alllll suggestions.
If any more information is needed, please let me know!
thanks in advance,
-Anthony
