The O ring on my TS-11 ....
I take it that you talk about the write protect ring on the back of the tape
itself.
I am happy to send you a few, if nobody nearer reacts (I am located in
Denmark)
Talking of tapes :
It is my experience that some flanges are deformed after some/many years, so
the flange scrapes along the drive. In this case, it is a good idea to take
a ring, rip off the "lip" sticking out, putting the ring upside down on the
tape, take another ring, rip the "lip" off, cut it, divide the ring into two
half rings, and stick one half of the ring inside the other ring. This will
lift the tape 1,5 to 2 mm (0,08" or so) which often is enough to remedy the
scraping
