What reference fluxivity should I use?

I believe it's 200nW/m for cassette, 250nW/m for open-reel. I once aligned a
ReVox consumer deck for Scotch ultra-high-output tape, and set it at least 6dB
higher. Otherwise, the meter would have banging at peak output.

The level for cassette is not really negotiable, because it's supposed to
represent Dolby level.

I has been fun reading this thread. My personal issue is where to get an
open reel (1/4 inch wide tape, 7-inch max reel size) setup and calibration
tape for my old Ampex AX-300 semi-pro tape deck.
