I am completely new to this forum and to B&O audio equipment. I need some help.  

I recently purchased a 5500 CD player which works very well and a 5500 cassette tape deck.  I connect the tape deck to a basic Onyko receiver with a connector that converts the five pin plug to two male RCA plugs. The deck appears to work well and does a fantastic job of playing old tapes (smooth motor, great sound), but it randomly shuts down for no apparent reason.  The shut downs can occur on play in either direction and at any point along the tape.  When it shuts down there does not appear to be anything wrong with the loaded tape and there is no jamming of any kind. Turning the tape deck back on resets it for new play and then another random shut down.  

I live in a rural community and there is no Bang & Olufsen store or repair facility anywhere near me.  My investment in the two used units was small and hardly worth the shipping fee to send the tape deck to an authorized repair professional.  The unit is old and expecting it to work at all at this point may be a bit unreasonable.  Nevertheless, I would love to be able to get a little more life out of the old, but solid, tape deck.

Any ideas what my problem might be?  Anything I can do to check things out or carry out some repair?

Thanks
