The whole point of the TCR's was to eliminate the need for making up spot reels! Of course the machines played directly to air, otherwise why invest the $$.<br><br>At WSNS we had the individual small reels in a room close by and on occasion would have to thread the 1200's when there was a cart jam. At KWGN and WGN there were multiple TCR's.<br><br>At WBBM there were 2 ACR's, one for spot playback to air and the other for news clips direct to air after recording carts from NX, the news tape playback room. <br><br>ACR was far superior, but then again double the cost of a TCR. Both machines totally revolutionized tape operations at V stations all over the country.<br><br><hr id="zwchr"><b>From: </b>quadlist-request@quadvideotapegroup.com<br><b>To: </b>quadlist@quadvideotapegroup.com<br><b>Sent: </b>Friday, August 24, 2012 8:32:44 AM<br><b>Subject: </b>[IS_SPAM] QuadList Digest, Vol 50, Issue 37<br><br>Send QuadList mailing list submissions to<br> quadlist@quadvideotapegroup.com<br><br>To subscribe or unsubscribe via the World Wide Web, visit<br> http://mail.quadvideotapegroup.com/mailman/listinfo/quadlist_quadvideotapegroup.com<br><br>or, via email, send a message with subject or body 'help' to<br> quadlist-request@quadvideotapegroup.com<br><br>You can reach the person managing the list at<br> quadlist-owner@quadvideotapegroup.com<br><br>When replying, please edit your Subject line so it is more specific<br>than "Re: Contents of QuadList digest..."<br><br><br>This is the Digest of the QuadList.

The reason behind this, similar to the network philosophy, was that these were high revenue generating commercials, where operational failure & "make goods" were just not option. <br> <br>-------------- next part --------------<br>An HTML attachment was scrubbed...<br>URL: <http://mail.quadvideotapegroup.com/pipermail/quadlist_quadvideotapegroup.com/attachments/20120824/38eebdfe/attachment-0001.html><br><br>------------------------------<br><br>Message: 4<br>Date: Fri, 24 Aug 2012 08:32:38 -0700<br>From: David Crosthwait <david@dcvideo.com><br>To: Quad List <quadlist@quadvideotapegroup.com><br>Subject: Re: [QuadList] Servo Modes<br>Message-ID: <2BE2E0DD-78A5-4160-9652-5BB7FC79A854@dcvideo.com><br>Content-Type: text/plain; charset="us-ascii"<br><br>I know of one TV station in the seventies in a top ten market who owned 3 ACR 25's. Two for commercial air and one exclusively for news casts. All film or ENJ were loaded to individual ACR cassettes and zero rolled during the newscast. I believe the TD was the newscast director. The anchor pitched to the story, then roll and take simultaneously. It made for a very tight and fast newscast.<br><br>One station in LA had ACR-25's then ACR 225's. There was not enough Kleenex in the house for the tears that were shed for years afterwards having to give up their ACR-25's. They eventually got over that by getting rid of the ACR-225's. <br><br>Regards,<br><br>David Crosthwait<br>DC Video<br>Videotape transfers and more!<br>david@dcvideo.com<br>www.dcvideo.com<br>Follow DC Video on Facebook: https://www.facebook.com/dcvideo<br><br><br><br>On Aug 24, 2012, at 8:23 AM, Trevor wrote:<br><br>> <br>> I was at an ITV network TV station with around 6 million viewers and yes we<br>> started live to air with TCR100's<br>> I think it fair to say TC100's are not as reliable as the ACR25<br>> RCA did not have good digital TBC<br>> The RCA Pinch roller less Capstan had its problems as did the cassette<br>> design<br>> <br>> Everything could have been sorted except for misinformation "pinch roller's<br>> do not go wrong"<br>> "The cassette box is not in circuit once the tape has threaded", were the<br>> main themes of misinformation<br>> <br>> When the engineer Bill ..... who's name will come to me turned and spoke the<br>> truth<br>> Changing Pinch roller capstan assemblies and rejecting new ones RCA sent<br>> and showing how to diagnosed faulty cassettes then they could have continued<br>> to be live<br>> <br>> Alas by that time the decision was not to go live but to copy breaks to tape<br>> and they were never used again live on air<br>> <br>> I do not blame engineers the misinformation came from the top of RCA<br>> Never went ACR25 they were replaced by BCN 100 and then Panasonic marc<br>> machines D3 decks<br>> <br>> TrevorB<br>> UK Member <br>> <br>> <br>> <br>> <br>> <br>> <br>> <br>> -----Original Message-----<br>> From: quadlist-bounces@quadvideotapegroup.com<br>> [mailto:quadlist-bounces@quadvideotapegroup.com] On Behalf Of Dennis Degan<br>> Sent: 24 August 2012 15:07<br>> To: Quad List<br>> Subject: Re: [QuadList] Servo Modes<br>> <br>> <br>> <br>> On Aug 24, 2012, at 12:50 AM, Wayne Watson wrote:<br>> <br>>> Also related to a similar thread we (an independent station with no<br>> network spot support) ran our only ACR direct to air for many years. <br>> It was something us techs were very proud of.<br>> <br>> I say:<br>> <br>> Not to throw cold water on it Wayne, but I don't know of a single TV<br>> station that DIDN'T run their cart machines live to air.
