First off. I love my amp. Crown rocks
Here's the deal. IThis amp is about 4 years old and in that time has performed flawlessly. Tonight at rehersal, I noticed that the channel 1 sound level was very low compared to channel 2. Noticed the fan was not running, but I understand that this will only kick on if necessary.
The amp was a little dusty, but never mistreated.
I did some swapping of cables to find that the channel 1 seems to be faulty.
I then removed the amp cover and did a quick examination to see if there were any obvious "fried" components.
Looking at the amp down from the front, I noticed that there were what appears to be 4 dabs of silicon on top of four components. I assume that the right side of the circuit board is for channel 1 and the left for channel two.
So here's my main question. The two dabs of silicon on the left (channel 2?) look good. The two one the right (channel 1) look very strange. The don't look silicon anymore. They look more like foam insulation. I believe what happened is that the fan failed and the two channel 1 components overheated the silicon rendering it into a foam. So what are these components?
Sorry for the long post :^|
