    I've never had to troubleshoot the PWM power supply module that samples the audio and controls the supply voltages by ramping them up and down at nearly 1MHz rate, so minimum voltage across the power amp module is held to around 10V at any time. I do have some of their service manuals, and have attached the Lab 2000 for more information on the subject.
