[QuadList] Another Weekend Quiz 04/01/11

[Chill315 at aol.com]

I have given this a great deal of thought.  I have studied the  literature. 
 I can not find this in any brochure for an AVR series.   Nor a 1100, 1200, 
or 2000.  So that leaves only the early machines.
 
I have never seen this in an Ampex machine but the TRT had it.  A  delay 
line to adjust for the quadrature errors in manufacturing of a head wheel  
panel.  The delay line was set playing back an alignment tape then setting  the 
delay or advance to get the demod out to look straight lines vertically  
between the head passes.  (Advance was actually less delay than the center  
position of the delay line.)  There were four sets of controls.  One  for each 
head channel.  The RCA machines that were prior to the TR-70 also  had this 
feature.  After you set these, you did the compliment on the  record 
delays.  It worked out very nicely.  
 
ATC, AMTEC and better manufacturing took care of this.
 
So 
 
Ampex
Delay setting
Unknown model

OK
 
This helps a bit.  I remember that there was an editor for the  VR-1000 
series machines.  And there was an Editec version.  So we  are going to go with 
that as the product and say it is Ampex, The first  Editec that was in a 2 
or 3 RU chassis and the plus or minus frame setting  knob.
