<DIV>Hi David:</DIV>
<DIV> </DIV>
<DIV>The VPR-7900 also allowed you to select head crossover positions for
compatibility with the "old" standard. Control track was also selectable
between the "old standard" 60 Hz and the "new standard" of 30 Hz (or 12.5 Hz for
PAL). </DIV>

<DIV>To tie this thread back to a quad related subject, here's a
picture of a VPR-7900 with the TBC-790. The quad relationship is that
the TBC-790 uses some of the same modules as the AVR-1 (but with different
trim).</DIV>

<P></P>The VPR-1 had a provision to either frame up the machine vertically when
playing the older style "dropout" signature tapes on the bottom of the screen or
the later recordings with the dropout (head switch) in the vertical
interval.<BR><BR>
