[QuadList] Ampex Quad VTR Airflow Requirements

[Roger Brett]

Hi Steve and Ted,

The machine is a "Merlinized" VR-1100, high band color unit.  The bummer 
is that I was reasonably familiar with these units back in the early 
'80s.  I keep hoping that if I stare at a reel of 2" tape long enough, 
that it will all come back to me...  ;-)

It's fantastic that you've rescued a VR1000C!  I'd love to see pictures 
of that unit sometime.  Do you have working video heads?
