[QuadList] Picture of the day (link to)---and who's in it?

[Trevor Brown]

Then I did the insert edit demo, and never switched the head back to record
position. 

 

We have all been there Glen on the TR70 its leaving the guide in auto so at
the edit point it stops hunting

and freezes in record, but always heavy followed by the next edit which is
even heavier ( you can end up slicing the tape)

 

We used to call it galloping guide and it always galloped in never out, for
some unexplained reason

 Hi Park,

I believe you are right, I never was involved Zeus other than a user. 
The big value related to not messing with the head was increase head life
when you did not change position of the guide. A coating built up on the
heads which created a protection layer. 

We would leave the head in the record position at all times unless I was
demonstrating the capability of the TBC to remove guide related errors.

I also did a demo where I would show recorded color bars and then due
multiple insert edits of other style bars to show the edit quality.

I made a mistake and after showing the guide error handling capability,
where both height and penetration were cranked to extremes. Then I did the
insert edit demo, and never switched the head back to record position. 

I made about 10 edits in a row, and went to playback and the Director of
Engineering ( Glen Lehman) for the group stopped me, and and took over the
demo. 

He got on the intercom, got everybody involved with tape into the demo area,
and explained that I had made the worst case edits that were possible, and
showed demod out, and then switched to the TBC out. Everybody clapped, and
then I figured out what I had done, which was very bad, but turned out
great!
He  explained what I had done accidently, later in the bar, with bar napkin
notes. Since, I was never a quad operator, I was keeping the Demo moving,
and made a true "Worst Case" tape and did not realize what I had done.
Needless to say, this mistake was included in all future demo's.

Bye for now, Bill Carpenter

I found the same thing with the NEC TBC on the Merlin retrofit. No matter
how off the guide are, the output is perfect. I have to look at demod to see
how the guides are set.

 

The NEC TBC is 10 bit. I don't think any Ampex Quad ever had a 10 bit TBC.
Wasn't the first Ampex 10 bit TBC the Zeus???


Best,

Park

And it also had the best video head life (no guide servo) since you could
leave the guide in one position and let the TBC and the AutoChroma do their
jobs
