[QuadList] Gene Kelley Show color recording system--which wasused?

[C. Park Seward]

Would the reason for heterodyne playback be because the time base  
stability was not tight enough and Colortec hadn't been invented yet?

While the TK-41 at the WRC dedication looked great, the tape had  
herringbone interference, probably caused by the beat of frequencies  
on the early machines. And it may have been heterodyne color. It  
certainly wasn't direct.

The "Kitchen Debate" tape looked great, recorded on am Ampex, but the  
camera looked poor.

Best,
Park
