SOURCE: Marantz Amp
hi, well done in diagnosing your problem:) From what you have just told me, the amp has noisy source selector switching, and may even have more than one switch or control causing the problem. Start with the source/direct button.
To resolve this, best bet is to "flood" the internals of the switch or control with CRC 2-26 . This will clean the contacts and leave a layer of lubricant to prevent the problem reoccurring, Getting the spray into the controls is the hard part. Check out what you find by way of entry points that you can get a the delivery straw into to spray. Sometimes you can use the a hole on the top of the switch, or "click" the top of it a little, enough to get the sray in. If the switch is a hermitcally sealed type, i have in the past used a pin vice and a very small drill to make a hole at the very back of the switch creating a place to get the spray in. Check it out and see how you go.
