Output Transformers: A Discussion of Basic Principles

2014-01-16 3,453 32 206,496 YouTube

In this video I attempt the unenviable task of trying to explain the design and function of one the most significant, yet misunderstood, components in tube amplifiers: the Output Transformer. Topics include: Purpose of the OPT, Winding Ratios, Demonstration of a Method to Measure the Winding Ratio, Consequences of Using Incorrect-Impedance Speakers, Impedance vs Resistance, Impedance Reflection, and how to select the proper OPT for your amp. Be warned: some math is inevitable, but I try to provide sufficient explanation to (hopefully) make it all palatable. Think of this as a video buffet.....consume it all, or simply pick and choose that which appeals to you :) If you enjoy videos featuring classic vintage amps, jukeboxes, homemade electromechanical devices, and clear, basic technical presentations, then please subscribe to my channel.
