I am at a loss to figure out how to calculate the output impedance of a tube or 
a pair of tunes.  I cannot find an old Handbook that had the information ((I 
think it is still packed from a previous move)   I I remember right...it has 
something to do with the operating HV potential and current.

I am looking for the impedance of two GI7-B tunes in parallel as I am getting 
ready to build such a beast on HF.  Just for the fun of it.

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.
