[QuadList] universal colortec (was why buy Quad)

[Trevor Brown]

When the major strike happened at ABC in LA in the early 70's, the biggest
video problem was that every control on the Intersync Servos, on every 1200
and 2000 was twisted to one end or the other by the tape operators before
they went on strike.
Most of the Supervisors had forgotten how to set them up, so there were many
calls to Ampex Tech Support, and some frantic Faxing of set up guides.

 

 

ITV had an 11 week strike and it took a lot of effort to get non tweaked
machines back on air

TR600's, the breaks rusted up, and the spool would not turn at all

 

TCR 100 well someone did remove the plastic  device that sits on top of the
guide to steer in the tape during threading

 

But we were not alone all the SPG's would not lock to subcarrier, if you
compared them on pulse cross to the BBC 

The ran through several lines in a second

 

AVR'2 I did install three in Kuwait city between the wars, they might have
cleared there archive now and have become surplus

Not sure if they would export to Israel  (no I do not have any contact
details)

 

They were PAL but could play back LB mono with a single card change I cannot
remember which card but it was a filter and the difference was only about 6
capacitors values

Very well stated Don,

I came into the broadcast marketplace in the last days of the 1200's, in
fact I was the last product manager. Then in early 1974, in Huston, Texas I
introduced the AVR-2 to the broadcast world. 

By today's std's I believe that the AVR-2 is the only machine for Shari to
by for this task.

The training curve to making good/great pictures alone is reason enough to
use the AVR-2

The DTBC was purpose built into this machine.

The servo system wants to lock up on most any Quad tape and deliver a signal
good enough for the DTBC, with a little help from the AutoChroma to make
very good pictures. And it does all this with no adjustments required.

I think the best endorsment for the AVR-2 was given by a competive salesman
(RCA) when an all RCA, southern TV station used a demo AVR-2 for a week and
was going to buy three AVR-2's. 
The good old Chief Engineer reasoned with the RCA salesman, and said that
the AVR-2 would playback any tape that he put on it with no problems or
adjustments.

The RCA salesmans response was " well if you really need a machine that will
play any tape, buy one AVR-2, but, buy two  TR-600's form me cause they are
cheaper"

I rest my case, and if you have any other concerns I will close with this
comment.

They never did solve the audio problems, since the audio folks just pulled
ALL the patch cables out of the patch bay and dropped them on the floor.

I learned all this from Len Bottom who was then in charge of all remote
operations (trucks) out of LA.

Bye for now,  Bill Carpenter

Shai:

The problem is that the TBC must be designed for segmented scan.  VERY FEW
ever were, and I'm not aware that any on the market today or in recent years
will work for anything other than non-segmented (helical) scan.

Universal colortec. I suggested to Tim that it might be possible to use the
regular TBC for NTSC and replace it with an external TBC like Kramer for
PAL. He was willing to try it if I hop over the Pond with a tape. If that is
possible it makes for one step to be a bit easier. This would make a good
multi standard machine.
