[QuadList] What is it????

[Don Norwood]

Hi Chris:

Bill can certainly address this more completely than I can, but the TBC-790 only uses some of the AVR-1 design.  Probably 70% of it is different.  The 790 was also soon replaced with the digital TBC-800, and when used with the 7900 or the console version 7950, they became VPR-7900A or VPR-7950A models.

  I saw the front extrusion and knew that it was the same as the VR-7800 and VR-7900 plus the AVR-2.  This style was also used by the audio people.  

  I was under the impression that it was a quad so that is why I went to the AVR.  I wonder how they were able to keep the cost down using the AVR-1 TBC design rather than another type.  This would be a question for Bill Carpenter.  

  I always was under the impression that the AVR-1 buffer was way too costly to manufacture.  That is why the ACR-25 went to the B model that had a digital TBC.  

  I await for the comments.
