Hey Folks,
I've got a KRK S10 Sub that had some intermittent crackling (more predominant on turn on).
But the power amp is working. I bought it used at a low price of $45 with this known issue.
I inspected the board:
Link Removed
Up Close here's the only obvious issue I saw:
Link Removed
Seemed like that Diode has some issues..
I sprayed some contact cleaner on it, and sure enough when re-assembled, the crackling went away... And there's no audio signal now. Getting power, just no signal. This being the last step in this particular series of components on the board leads me to think I might be able to cure this with a few surrounding caps, diodes or resisters.
Couple of questions come to mind in the spirit of: (I don't have the $190 to replace the whole back panel, and I've got to brush up on my component t-shooting skills)....
I'm basically looking to ID parts accurately, find a good source for those parts, and give it a try...
Thanks so much in advance of any advice you have!
