tungsten tubes - An Overview
Typical values of gm for a little-signal vacuum tube are 1 to 10 millisiemens. It has become the a few 'constants' of a vacuum tube, one other two currently being its acquire μ and plate resistance Rp or Ra. The Van der Bijl equation defines their marriage as follows: g m = μ R p \displaystyle g_ m = \mu \around R_ p Some in any other case conve
