It all depends on the use.

For archival preservation copies, I don't touch EQ or do anything, 
thereby allowing some future engineer the opportunity to use better 
tools than I have available in the future to do something without having 
to undo anything.

However, for many projects, I deliver a preservation copy and an access 
copy which is EQ'd, de-noised, and whatever else is needed.

Of course I try to set the correct tape playback EQ (NAB/IEC) or some of 
the other variations listed in IASA TC-04 and use my ears for that, but 
keep it standards-based.

Noise reduction like we're talking about is a big concern, which is why 
I provide a raw and a noise reduced transfer, again, so no one has to 
undo something I did if it was wrong, and undoing NR is no where near as 
easy as undoing EQ.

Quality tape transfers -- even from hard-to-play tapes.
