(score: 1): Author: 2@vc.net (2); Date: Sat, 28 Sep 2002 16:23:40 -0700; ** <11kV is supposedly safe, unless the tube is gassy -- i.e., the anode conducts via gas when the grid is in the cutoff region and the tank swings positive. Thus, one can have current flow at c. 19k; /archives//html/Amps/2002-09/msg00266.html (7,870 bytes)
