answering machine beeps--then shuts off?

One of the thin belts that drive the tape has broken .I have the same model . I have just replaced the last belt I had ,but I am having a hard time locating replacements . It has been a great answering machine for over 20 years or more that I've had it . If you know where belts can be purchased for the code-a -phone 2530 please let me know.
thank you
