[Amps] GI7B Question - Input Matching

[Lee Buller]

I have been reading about the GI-7B Russian made tube.  It seems that the input impedance of two tubes is around 100 ohms.  Could you not just use a 2:1 transformer to make a match from 50 ohms to 100 ohms?  What am I missing here.

In our day and age it seems that Common Sense is in short supply.  If you don't have any Common Sense - get some Common Sense and use it.  If you can't find any Common Sense, ask for help from somebody who has some Common Sense.  Is Common Sense divine?

Common Sense is the image of the Creator expressing revealed truth in my mind. -  J. Wolf
