Aligning any of the Fostex 16 track machines is a bit of a pain because you don't have
separate record and playback heads. So you have to tweak something, record a test tone for
a few seconds, rewind, playback, rewind, tweak again and repeat until you've found the
optimum setting for that control. You then move on to the next control. The procedure is
described in the owners manual and in the service manual - I don't have a B16 manual but I
have a .pdf of the E16 service manual (which is big) so let me know if you would like a
Edit - just found the B16 manual at
but it is a bit vague on the exact calibration procedure.
I'd be tempted to just try a reel of RMGI tape, record a frequency response sweep
and if the level is within 3dB between 250 and 10kHz (as suggested by the service manual)
assume that the bias is OK.
