Re: [ARSCLIST] Reel-to-Reel Tape Problems
I have had a similiar problem with the Quategy 499. I have debris shed
on the guides as well. I agree that the QA isn't as good on the 499. I
have also had problems with it being just too wide that is sheds a
tiny layer from the outside. I don't think they are as precise in
cutting the tape and inspecting it as other formulations have been in
the past. The good news is I haven't experienced this on all the tapes
just certain batches. When we do find a tape that seems not to be up to
quality we just put that box away and try from another batch. The tapes
just seem to be very inconsistant some of the batches seem to work like
they are supposed to. I think if all of us that use the tape started to
complain back to the manufacturer at once something may be changed on
their end. However since I have had this "revalation" I haven't had the
problem with anymore boxes of tape haha.
