Hello! Boy am I happy I found this community! my rig - Onkyo TX-NR636 Klipsch RB-41 II Bookshelf RS-41 II Surround RC-42 II Center R-110SW Subwoofer And its mr subwoofer that's giving me grief. HUGE CRACKLES. ON - crackles AUTO - quiet if switching from standby, continues the ol' snap crackle pop if coming down from ON STANDBY - quiet not connected to either input levels all turned down. I tested in my neighbors house, so I'm pretty sure the electric is OK. Any ideas/suggestions? Any multitester type things I can test? Thanks in advance, Evan
