What kind of gain can I reasonably expect from a GS-35B on 6 meters at anode voltages less then 4 KV? The info I have found on the web is sketchy and inconsistant. Most builders seem to avoid the issue of gain. I have a number of options for the tube(s) in this amp project and am having a hard time deciding which to build. 73, Larry -- Larry - W7IUV DN07dg http://w7iuv.com
