Tubes becoming microphonic


I own a CARY SLP-05, this is my first experience with tube equipment. I recently read a thread and the person mentioned his tubes became "microphonic". How can you tell when your tubes become "microphonic". What are some of the leading signs. Thanks

My experience with microphonic tubes was I first heard my volume knob being turned in my speakers, with a slight "ping" sound.
