Hi people, I have this sub, only issue is when I bought it, it had a very loud hum. The previous owner had it repaired which lasted for 8 months odd. I looked inside and caps look normal, no swelling but on the rear side of the only circuit board is a few IC chips, 1 has what looks like a burnt chip, instead of it being black, you can see the metal under that.
Also, whoever repaired it did not bother to secure all 3 cables which has double sided tape on, 1 of which is very close to the live input from the wall socket cable, whether something has touched it, is a possibility.
Can ic chips be scratched, scraped and still work ok?
Other than that it looks ok inside, but worth pulling the main caps out of circuit to test?
