Hear Amp Distortion - Crest 4801 (Public)

Sammy joins me as I start testing a way to directly hear amp distortion. In this first video we test a Crest 4801. I will be doing more in depth video on amp distortion testing a Lab Gruppen 6400, and Powersoft X4

The way amps distort is quite different and this exposes another interesting aspect of audible power supply ripple.
