Re: [ARSCLIST] scotch 227
Hello,
I should also add that although my transfer was succesful, I also still
had a considerable amount of residue on the tape guides and the heads. I
was just happy to get the tape transferred without any squealing, and it
doesn't seem like the residue affected the final transfer dramatically.
I don't think I could get it any better.
Regards,
mike

Following up on this, even after all that baking and cooling, there was
a little residue on the
guides after the reels passed. The residue seemed to come much more off
the back-coat side -- very
little of anything on the heads or takeup guide but some crud on the
supply guide and pinchroller.
Not enough to gum up the works but more than would be expected from one
pass of a good tape. Got a
good transfer so hopefully that's it for these tapes. Made a safety dub
at the same time, onto
supposedly "cured" Quantegy 457. Check back in 10 years and we'll see if
it's really cured.
