<DIV>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?</DIV>

<TD vAlign=top>Hi Folks,<BR><BR>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.<BR><BR>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.<BR><BR>The machine had a dual track audio system,
with the electronics above the top plate on the left edge.<BR><BR>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.<BR><BR>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.<BR><BR>Bill
