In Reply to: How are they conncted in a form of UL when G2 posted by Michael Samra on August 8, 2016 at 11:31:36:
True pentode mode requires that the voltage betw g2 and k be held constant under all possible conditions. While the the SA1000 circuit holds g2 voltage constant wrt ground, the voltage betw g2 and k varies in step with signal because the ks are tied to a winding on the OPT and are not at AC ground potential. Net effect is that g2-k voltage varies at some proportion of a-k voltage just like conventional UL.
