Thanks to Bill for his great first-hand stories!  Here's a pic of the color stabilizer installed in a VPR-20.

  Hi Folks,
  The Ampex VPR-20 had a Hetrodyne color adapter which allowed you to playback color in the field for review purposes.It had a RF (channel 3 or 4) output, I used it at NAB in 1981, on a hand truck type of camera/recorder roll around remote which I built with a 12" Sony TV set. 

  We would show it side by side with a 19" Zenith TV set next to a color monitor with the same output fed thru a external TBC in most trade shows.

  It was based on a chip, probably from National Semiconductor.and was packaged in a shielded metal box and was about 3" x 9" x 1/2" and it was an option which fit inside the case, This was an Al Trost design and worked very well.
