Hello all,
I have a Sansui AU-a907 audio amp. It sounds really really good!! A little problem is that there's about 250mv DC output at speaker terminals. I adjust it close to 0mv few times but when I turn it on the next day, it's out of wack. Both sides
This amp has Integrated and Power amp direct option. When I adjust the DC offset at Integrated mode and move the dial to Power amp direct, then the DC offset goes to around 200mv. Both sides
Anyone has any suggestions on where I should look at?
You can look at the diagram here
