[QuadList] Question of the week

[Bill Carpenter]

Hi Don,

Yes, the Al Trost signal system from the AVR-2, was repackaged by Maurice and added to the DTBC, which had a 45 degree sloping mount on top to accept the VR-3000B. 
I believe the system was shown at Montreaux in 75?

Bill:
 
Thanks as always for your informative post!  I don't have any "B" 
version 3000's, but I do have a manual for the B and always wondered, since the 
head signals were available, did the Ampex package use external 
switching, demod, etc before the TBC, or was the video out of the 3000 fed 
directly to the TBC-900?  It seems like the only way to get "AVR-2 
performance" would be to have an external signal system, but if so, was that 
another box or was it packaged with the TBC-900?

      Hi Folks,

The VR -3000B did not have a plug-in 
        DTBC, it used a TBC 900, which was also the base for the unit, when 
        playing back to air.

I gave a SMPTE paper and showed the system @ 
        The Winter TV Conference in Detriot in early 76, which many called the 
        birthplace of ENG.

The machine had a dual track audio system, 
        with the electronics above the top plate on the left edge.

The 
        system, the VR-3000/TBC-900 was a joint venture between Al Trost & 
        Maurice Lemoine to produce what was wanted in France. Additional 
        connectors were added to bring the video head signals out to external 
        processing and the goal was AVR-2 playback performance.

The 
        goal  was to use the VR-3000 in the field and then at a mobile 
        "base station" use the TBC-900, to feed a high quality signal back via 
        microwave to be broadcast without further processing.
