In August 2012 I start with building linear’s. I start at first with one Russian GI7B tube. I finished it in December 2012. I have no pictures any more from the building phase, but I can show you what I have.
With this linear you can make 350-400 Watts on SSB.

I sold this linear, after a longer usage.
