Default Re: Mark Levinson 436 problems

I did try swapping the speakers, swapping the power cords, swapping the interconnects. The only swap that had any effect was swapping the interconnects and the power cords at the same time. Doing so restored normal function for a few hours, or a few days; but then, the power indicator light on the front of the amp dimmed, and when I tried to bring the amp out of stand-by, the amp failed and continued to fail. My technician at the local ML dealer suspects a circuit board that is discolored, but ML will not provide one under warranty from the upgrade. This board was not replaced during the upgrade. I may have to buy it myself. Any experience with similar problems out there? I thought that buying amplifiers that cost a lot of money would mean that they would last a long time.
