I have had good results using the TWO center tracks, but one must align azimuth very carefully to
the tape being played. A scope can be helpful but I prefer putting one track out of phase and tuning
for maximum null. And make sure to re-check azimuth if there is leader or another known incidence of
recording being hit at a different time or location from the section of tape you just played. If the
azimuth is right, summing those tracks to mono makes for better s/n and less too-much-bass.
I should note this does not work if the full-track tape is not being brought over the heads
precisely. In other words, if the tape is stretched and warped badly, stick with the single
best-sounding of the 4 tracks.
