Hello - I posted earlier about my Marantz 9200 starting to buzz a couple of weeks ago - the unit itself, not thru the system. After going thru all possibilities, it finally came down to be caused by a standing floor lamp in the same room This is a simple incandescent lamp - two 60W bulbs, no dimmer - with a two position switch (bright and brighter). The recvr buzzes more at the lower brightness than full position (sort of like a dimmer, eh...?). If the lamp is on, having my 9200 plugged into any outlet in my house causes it to buzz - even in a different room. And vice versa... Since it's a cheap lamp, I know I can get rid of this problem by trashing the lamp - but I'll need something to read by in the room Any suggestions to eliminate the problem with either this current lamp or any future ones I buy to replace it - short of a dedicated line? Thanks!
