Hey All,
I have a MA6200 on the bench and the Power Guard LED on one channel is turning on a fairly low volume. It's definitely something the driver board because I can pull both boards and switch left for right and the LED follows the board. I have checked the transistors in circuit and they appear okay. Any ideas?
Also, does anyone know the bias adjustment procedure? Hifiengine has the schematic and the owners manual but neither shows bias unless I'm missing something.
Thanks
Matt
