The AU-D22 is a small model in the AU-D Line (the top model was the Excellent AU-D11) that dates back to the early 80's.
It sounds like some components somewhere inside are acting up. A service manual which includes schematics is available on this site- simply check the link in red ink on the homeage and scroll down to the AU-D22 in the Manuals list.
