After the Part I has been done, now I continue to the Part II. On this 2nd part, I will see what’s wrong with the Marantz PM400AVK.
Simple testing method is to try it on other speaker. Initial diagnosis is the volume control problem, as I could hear some cracking and intermittent no sound on the speaker. But sometime the problem could be solved after turning the volume up and down. Definitely, initial problem is on the volume control. So let’s take a look inside.
