Hi all, I'm having a problem with my Marantz 2200 and looking for guidance. Just recently I started getting a static-y noise/popping just on the right channel. A few details: - It is not affected by the volume or selector switch (phono/AUX/FM/AM). - The static persists in the right channel for a minute or two after I power down the unit. - Can be heard on main speakers, remote speakers, and headphones. - Switching the speakers revealed it is in fact the receiver, not a speaker problem. - I cleaned all switches and pots thoroughly with deoxit. The problem seemed to lessen for a few days, but it came back. Anyone have an idea what this could be? The receiver is probably due for a recapping, but I don't want to do a full overhaul and find out it was something else. I seem to recall from another thread that if it is apparent in headphones, that indicates a fault in the amp, not preamp. Maybe DC offset or a leaky transistor? Any help is appreciated!
