Questions about tubes and gear that glows. FAQ

Correction! NOT!

This is amusing and it drives me crazy which drives you crazy. The answer to the capacitor ratios that I calculated before seems actually correct, but I arrived at the answer in inverse fashion, turning the equations around.

Here's how I do it in a more "correct" straight forward method:

Gain is Av, not Av-1.
C1 = Ck/((1-1/Av)Av) to achieve G in flowchart = 1.

If you run the numbers through you get the same answers as I originally showed for the different tube stages.

Oh well, no change in essence. Have fun trying this on your amp if you choose to do so. I hope I am right this time. :-)

How it's supposed to work with PP is not known to me now.
