[Moon-net] Input impedance of GI-7b and GS35

[Kim Liljekrans]

HI Horta, PY2NI

The Input impedance of a tube is almost infinite  of tubes in the 1 GHz 
region !!

Its the surrounding components, who almost is the determine factor . So dont 
think of the tube itselves.

I would say, that below ie 2-300 MHz dont thinkof it, but only of the 
capasive part if any !

GL with it,
