REEL ACOUSTICS RSW-12. Started making a fast knocking noise out of the blue, unplugged rca cable, no change, had to unplug it from outlet. Plugged into another outlet in garage, no sound, took it apart one ground looked loose from the power supply so I tightened it, looked at the board couldn’t see anything, plugged it in, same noise. Took it back apart looked more closely and found this burnt.
The blade connectors go to the speaker, just below the resistors is what you’re looking at. It looked burnt but hard to tell, so while it was unplugged I took a very small screwdriver and touched it and it just crumbled, I scratched at it a little bit to see if there was still anything between but nothing, it’s all gone.
What I’m wondering is what is it? Could it be the cause of the repeated knocking sound and how am I supposed to know what to try replacing it with when there’s nothing left of it and I can’t find a schematic anywhere online? Any thoughts, suggestions or help appreciated.
