Kennedy 9600 (A) woes

Hiyas, Does anyone have experience with troubleshooting Kennedy tape drives? I have a 9600A here (still needed for reading in that darned UNIX tape...) and although it seems to work, it does fail one of its self tests (FAIL 153, second code is A50-NRZ1) and indeed does not read tapes, *nor* does it "see" the write enable rings. All other things seem to work fine. Any help would be muchly appreciated... if anyone has a scanned manual for it, that would even be better !
