Hi I have a Marantz NR1501 Amplifier 7.1 with a Jamo 5 channel speaker system.
For the past week of so I've been getting a crackling popping sound randomly coming from all speakers including the subwoofer, so I checked on another home theatre forum and I found several similar problems one of which being blown capacitors due to surges this could be the problem, because I leave my amp on when I leave home(not any more).
So I opened it up to check if any of the caps are bulged or opened or if there is any visible fluid at the base, I came across this (Addendum A) not sure if it's dielectric or some sort of adhesive.
Addendum A:
Another reason for this as suggested by one of the posts on that forum was that the speaker wires are too close to the AC/power cable which stands for grounds of mutual inductance right?
This is a really expensive system and I just realised I had it connected incorrectly for 3 years I had the surround speakers(High signal) connected to the Subwoofer(Low signal) could this have damaged the amplifier due to poor impedance matching? If so can I take it to my local repair man to let him sort it out?
