| There have been some great comments recently on tubes and IMD curves.  I am 
just getting into looking seriously at amps, and I am trying to absorb as much 
as I can from a lot of brighter people than myself in this reflector.
The Russian GI-7B tube looks like it would be an interesting tube as a 
replacement for the 811 class of tube.  What I don't know is since it is a 
'microwave' tube, would it work well in HF and SSB?  I 'assumed' the gain would 
increase at lower frequencies, and therefore be a good candidate?  The typical 
data sheet for a GI-7B does not show any IMD curves as was discussed recently 
with the Eimac tubes.  I know there are tube conversion articles out there 
using this tube, but from a 'quality of signal' for lack of a better term, do 
some of you more learned guys know if these tubes are really applicable and 
produce a good clean signal for HF CW and SSB work?
Thanks in advance for any responses received.
    Dennis, NU8S
