Guitar Amp Vacuum Tubes Part 1: Triodes and Tetrodes

In this 2-part video presentation, I discuss the characteristics and evolution of the vacuum tubes used in vintage and modern guitar amplifiers. Beginning with Triodes, the general design, strengths, and weaknesses of each type of tube will be discussed, and terms like secondary emission, parasitic oscillation, negative resistance, and inter-electrode capacitance will be discussed and (hopefully) clarified.

If you enjoy videos featuring classic vintage tube amplifiers, jukeboxes, assorted homemade electromechanical marvels, and clear, basic discussions of technical topics, then please subscribe to my channel. You will gain access to well over 100 videos and will be notified each time a new one is released. Thanks for watching !!!
