This makes me wish I had kept my big mouth shut.
The tape was obviously not a primary source and was required urgently.
The job was done in 1990. My A700s gave good results, and occasionally
still do. I had sense enough to keep the stuff off the lower reaches of
the capstan and the rest of the clean-up was not problematical. This
forum is for the exchange of information, not for sniping.
