crackling sound out of right speaker

Maddog66blue, you need to identify the problem component. This is done by a process of elimination. Start at the source, and swap the L and R interconnects. If the problem doesn’t shift from one speaker to the other, then the source component is not at fault. Move to the next component in the chain, and repeat the process until you notice a shift in the problem..

The final test would be to swap the speaker wires from L to R etc. If the amp is at fault, the problem will shift to the other speaker. If it doesn’t, then something is wrong with the offending speaker.

It maybe your preamp volume control. Try to jerk it up down. Also to make sure, if you have any other preamp or receiver, you can connect it onto your system and see if problem still there.

Hi Marakanetz, I'm not going to jerk it up and down, however I did adjust the volume and didn't notice any difference. I don't have a replacement preamp or receiver, I'm going to be bringing both the preamp and amp into the shop for testing.

Excuse me boys, but if the problem did not jump from R speaker to L speaker, when the OP swapped speaker cables from R to L and L to R, then he need go no further; the problem is in the speaker. This is assuming I have the correct understanding of what was done. Brf keeps saying this, too. I agree with Brf, but it's not merely a matter of opinion.

Dear Maddog, It would make sense to seek outside help to evaluate your speaker. Perhaps your dealer can help. One thing is sure: none of us can help from this distance.

No I didn't swap IC's, just the speaker cables.

Does this mean that you interchanged L & R at one end of the speaker cables, so that what had been the right amplifier channel was then connected to the left speaker, and vice versa? Or does it mean that you literally swapped the speaker cables, changing their connections at both ends, so that what had been the right amplifier channel was still connected to the right speaker?
