[QuadList] VR-1200B Daily Servo Set UP

[dcfwtx at aol.com]

 In the mid 60's, CBS and NBC had individual modifications to the VR 2000 that they frequently shared. CBS was notorious for modifying just about everything when it came into the door. Many of these mods were incorporated into later production models, such as the VR 2000Bs.
