I am sure there was a service manual for these, RS had
a service manual
for
almost everything they sold back then including stuff
like
calculators!...I
actually bought a lot of about 300 at one point and
threw them all out
after
a few years not using them....
Thanks for the reply

Contact RS, they may still have manuals.
The TEC201 is unfamiliar to me but the mechanism sounds like the Shugart
by a different name.
The alternate solution is a newer 48tpi drive jumperd as needed.
