I have a JBL Venue Sub12 with a bad amp. It powers up just fine but after about 10 minutes of being on or getting a signal, it starts poping. I took the amp out and noticed some black spots on the back of the amp board. I'm wondering if replacing the compacitors where the black spots are will fix the issue. There is a guy on ebay that will replace the amp for $140, but that seems pretty expensive if its just a couple of bad transistors.
Here are some pictures of the board.
Any idea on how I can figure out what type or model of compacitors that are?
