Hi
Actually, my first concern is the analogue tape itself and then the
equipment, simply because the machine can be fixed by the terrific
technicians stil alive and available to do this because 'they know' what the
heck they are doing. Tape problems are a different factor in the mix given
the different brands, etc, etc, and many of us are trying to address this in
our own way and on an international basis.
Corey, please tell me, what are the ingredients of the Last Factory stuff
you use? Do you know?
Cheers
Marie
