Replacing the selector switch shaft on a Marantz 2230 is a relatively simple repair that can be completed in under an hour. However, it is important to note that this repair should only be attempted by those with experience in working with electronics.
The selector switch shaft is a small, metal rod that connects the selector switch to the main circuit board. Over time, this shaft can become worn or damaged, which can cause the selector switch to malfunction. If the selector switch is not functioning properly, it can prevent the user from selecting the desired input source.
