Topic 69: JCM 800 Preamp Analysis

This video presents the analysis of the preamp section of the Marshall JCM 800 amplifier, with master volume. The DC and AC load-lines of both stages are plotted and the voltage gains are determined, step-by-step. The techniques and concepts developed in the previous tube-related videos are used here.
