My marantz 4300 needs cleaning

[Carito05]

Hi, everyone! I know this is an old post but I'd like some info on how to go about how to properly open up a marantz 4300 that I picked up. It's pretty dirty and I'd like to try to clean it up a bit. Any help and advice would help. Thanks!

Hello Carito05. Welcome to AK. Found the Owners and Service Manuals here. There is a diagram in the SM of how the receiver is put together. http://www.vintageshifi.com/repertoire-pdf/Marantz.php. For cleaning the pots and switches DeOxit is recommended. Check the thread on using DeOxit in the"General Audio Discussion" forum.
