Question about Marantz ST4000 2 Channels Tuner
Sounds like cold solder joints inside the unit...if you know how to solder you can take unit apart...look at the main pc board and see if you see some connections that look like they have cracks in them. A solder joint should be shiny and solid...if it looks like it may not be solid and shiny you can resolder it to make it like new again. This may solve your problem
