I recently inherited a Tascam TSR 8 that I was planning to incorporate into
my digital setup. Scott Fraser just happened to be unloading several reels
of 1/2 inch tape which has prompted me to make this all happen sooner rather
than later. He gave me several reels of Ampex 456 which is what I was
planning on using. He also gave me many reels of 3M 806 which we were both a
little foggy on. Can I use 456 and 806 interchangeably or does some
recalibration need to occur?

Thanks,

Neil R
