I believe you are correct on that, but there was a Low Band Color  
demod board set available for the AVR-2. These could not be used for  
recovery of Low Band Mono though, due, I recall, to differences in  
carrier freq and deviation.
I had very limited success playing Low Band Monochrome tapes on AVR-2  
by taking its demod out to an external proc and TBC. Had to be very  
careful about skew and scallop (tip penetration and guide height)  
which, if off even a little bit, would cause line pulls at each  
channel's head switch point.
I also had 7.5ips 5 mil head recordings. With only a 10 mil head  
available for playback, I had to manually, carefully, ride tracking  
to minimize (of course never eliminate) moire and interference  
between tracks. Since the content overrode the technical flaws, the  
recovered video was adequate for the purpose needed.
