In this Part 1 video in a series featuring the scratch-building of a high-wattage single-ended KT-88 and two parallel 6L6GC amp, we will discuss the circuit features in detail, construct the entire chassis with a ventilated floor panel and EM shield, discuss the differences between SE and DE output transformers (Jack's Geekfest), and finally take a harrowing trip on Mt. Cristo Rey.
