"I agree with tom about the output transformer being the main source of audible distortion, especially frequency response distortion in vacuum tube amplifiers. The main culprits seem to be eddy current and hysterisis losses in the core. B-H curves even for supermalloy are less than ideal probably orders of magnitude worse than the nonlinearities of either most tubes or transistors."And then there's McIntosh output transformers. Do they have the same characteristics?
