Re: [ARSCLIST] S-S-S and tape baking

[Lou Judson <loujudson@xxxxxxx>]

A radio company I worked for in the 70s and 80s used hundreds of boxes 
of Shamrock - which we knew was cast off and substandard Ampex, but 
they were on a tight budget - and all of it had brown oxide and black 
backcoating, except a few random reels that were not backcoated. All 
was 1.5 mil. Much of it is what I now have to transfer to digital, and 
some of it is nasty stuff.

Fortunately they switched to Scotch 176 and all of that has been 
excellent to play now, still "broadcast quality" as it ever was even 
though it was duplicator tape.
