Thanks to this really helpful group, I am now learning all about SSS and that I'll probably have to ditch most of my old Scotch and (maybe) TDK tapes after recovering any irreplaceable programming from them. Fortunately a great deal of what's on those old tapes are copies of the records I bought back then and I still have many (but not all) of those and I'll be setting up a refurbished turntable soon. Something I've not heard or found yet is a list, if one exists, of what studios used what types of tape for the pre-recorded 7" reels. I have a number of those and there are at least some that I'd like to keep & use if possible. I have a bad feeling that a lot of studios like Capital etc. may have used tape from Ampex and from what I've read, they were one of the worst offenders in the use of binder that breaks down. Is there any way to know what tape was used for a given recording ?
