Hi Goran Thanks for the info. Re. Agfa, we've had several examples of PE 49 (double play, 7") which have proven sticky. According to the numbers in the green leader tape there were two manufactured bad batches at least, both seemingly bought by us at the same time, circa mid-1988. The numbers to beware of are 01041 and 15383. All other PE 49 batches thus far have been fine.

Will Prentice: > Responding to Richard's comment that "all tape > manufacturers seemed to have created batches of > tape which suffered from this [i.e., SSS]" I have never ever seen any BASF tape ever go sticky shed. BASF is one of the worlds biggest chemical companies. They have always claimed that they had all the knowldedge in house together with making all the ingredients in house. So their position is that due to the above none of their tapes will exhibit sticky shed as they knew how to avoid it. AGFA, it is the same except for some batches of Agfa 468 during half a year or so. I have only seen one real of 468 go sticky despite having transferred several hundred such reals over the years. In contrast it is almost a given that any reel of Ampex 456 will go sticky for sure. And that is true over here since so far they all need baking. -- Best, Goran Finnberg The Mastering Room AB Goteborg Sweden E-mail: [log in to unmask] Learn from the mistakes of others, you can never live long enough to make them all yourself. - John Luther ************************************************************************** Experience the British Library online at www.bl.uk The British Library's new interactive Annual Report and Accounts 2007/08 : www.bl.uk/knowledge Help the British Library conserve the world's knowledge.
