Of course the analogue source should be preserved. With it should be an
analogue copy of practical quality. In the same transfer which generates
the analogue tape, a digital recording can be made on a standalone
recorder. The original should be archived for that day when better
extraction can be tried despite its degradation over time. The analogue
dupe can be used or preserved as appropriate. But the digital capture can
spawn all the copies one desires for archives, for enhancement or for
whatever other purpose. So the solution for that woman would have been:
have someone who knows how set up a single transfer from which further
action can be defined at will.

In the limited work I have done with such materials, I've found that there
are two extremes and a range in between. One extreme is: give me the raw
material and I will see what I can extract. The other is: Make it
listenable to modern ears accustomed to DDD recording. With the undoctored
digital dub, each user can produce what he/she wants but the original is
not compromised.

I know that all that is self-evident. However, sometimes even the obvious
is worth stating.
