[Amps] Input Z for 2xGI7b

[Johnnie Walker]

Gentlemen,

What's the concensus on the input resistance of a pair
of GI7b? 

For the resistive component, I've seen numbers in
quite a wide range - 
from 30-145 ohms.  That's quite a spread!

I was hoping that the range could be nailed down more
closely for the 
design of the input matching network.  Perhaps someone
out there has 
been there, done that.

Thanks!
