tungsten tubes - An Overview
regular values of gm for a little-sign vacuum tube are one to 10 millisiemens. It is amongst the three 'constants' of a vacuum tube, the other two getting its obtain μ and plate resistance Rp or Ra. The Van der Bijl equation defines their connection as follows: g m = μ R p \displaystyle g_ m = \mu \above R_ p The ability of boron carbide to soak
