Re: [ARSCLIST] Ampex 456 - tip of the iceberg...chemistry
This could be some valuable information for the group. Interesting about
the lack of problems after the packaging change...I wonder if they
changed something in their slurry or coating line at the same time.
Also, I may have a line on actually reaching someone who was with BASF
for a number of years before they exited the tape business. If anything
of interest comes to light, I'll post it.

Actually, my only experience was with 1/4" and 1/2" tapes. I also
noted that when Agfa had switched their packaging (I guess around
1990), the 469 didn't have any problems after that, at least up 'til
1994. I did put together a database of the tapes we handled, sometimes
having to guess the year of recording. I will try to get access to
that data again, to see which years were involved.

Your observations regarding 468 and 469 are similar to the
experiences I had with some batches of stock (in all widths) around
the mid-to-late 1980's. The stock we received prior to this time
period seemed to be fine, and the tapes I still have on the shelf
which date from about 1979 to 1985 all play fine, as do tapes from
the early and mid 1990's.
