Good Evening All:
I found this group while searching for information on the Gi-7b Russian tubes.
So, here is the question. Has anyone used the Gi-7b in an amplifier? I am in
the process of building a new amp for 6 meters using a pair of these tubes.
What kind of output did you get, and at what efficiency? I have seen data
saying anywhere between 700 & 1200 watts for a pair at 6 meters, and at
efficiencies from 57% to 68.5%
Did you burn the tubes in before applying HV and drive? What was your burn in
process?
Any input would be greatly appreciated.
73,
Mike, W5UC
