I am having trouble locating the information regarding repairs for a Beocord 5500. The player works fine, but the belt that retracts the tape deck from the case is either broken or off its track. Any advice on where to get another belt or on how to repair would be appreciated. 

Note: My repair guy in San Diego refuses to work on these units anymore and is a contankerous old fart. I would prefer not to send to Chicago for repair, nor beg locally to have it done. 

Any advice or redirect would be appreciated. 

Thanks in advance, Beau
