[QuadList] WRC B/W to Color Quad tape

[Charles Park Seward]

Hi Ken,

Hope you are doing well.

I have a question about the early color recordings. I have some low band color recordings from the middle 60s and I see a lot of herringbone interference. Is that because of the frequencies they used? Is there a way to clean that up? 

Best,
Park

The tape that I received is the WRC recording and the one that Ed Retain, Don Kent and Dan Einstein did was the one from Ike's library. The WRC tape was played many times before we at Merlin received WRC's tape. So the WRC tape had some tape damage to it. I built a special demod demphasis for the this tape. I later learned that RCA had two Ampex VR1000's with the signal system removed and RCA signal system installed, as the Ampex had a very stable servo and RCA did not. That hey the audio lip-sync is correct on that tape, Ampex had not change the position of the audio with respect to the video, but
