Rotel RSX 1056 RDV 1045

I picked these up at the thrift the other day with the 1050 remote. And of course the 1056 has the clicking speaker issue. It's minor, and sporadic. Instead of a new board is the a part that can be ordered to rectify this?
These units were quite inexpensive so I have no complaints. The 1056 does sound excellent. And the DVD player works fine as does the remote (No light on the remote and the laser cover is missing).......
