    I think I've found this pair...the whole wheel came out when
unscrewed...connected to a plastic strip on the bottom. Cleaned this pair. And
managed to get the tape out more or less intact.

    Not sure about this one...

    I take it you think the tape isn't worth feeding back through?

    Another curious thing...after I got the tape out, I tried to power the unit up
again. Same thing happened...three short jerks on the spool, and then the
flashing red light. I checked the phototransistor and LED...they seem to be aimed
through the hole in the guide belt. Is it possible that one is not working?
