I ran into a similar situation with some Soundcraft tapes years ago.
Probably mid-fifties vintage. (Don't recall the oxide # right off hand)
As I recall, I think we ended up having to hand wind most of them (this
is way before we had special transports for cleaning), and cleaned and
lubricated the oxide. I spoke with whoever the rep was at Soundcraft at
the time, and he mentioned that he had heard of some cases of acetate
tapes that had some issues with lubricant. He didn't come right out and
say they were defective from the plant, but that is what I surmised from
the conversation. There were other tapes from the same collectionwith
the same oxide, which had no problems. I also have some tapes in my
personal collection from the same era, and when I played a couple of
them last year, experienced no issuesbeyond some minimal base warping.
On the other hand, we have done transfers of some Soundcraft 35mm mag
from the same period, and boy did it stink!
