<DIV>Hi Chris:<BR><BR>I can answer some of this....</DIV>
<DIV> </DIV>
<DIV>As to the A/D convertor, the the engineering drawings are dated ‘79 and
‘80.</DIV>
<DIV> </DIV>
<DIV>The sloped transport was easy to do with the design of the Ampex “cart”
that the deck sits in. Add a wedge or some type of support bracket and you
could have the transport sloped very easily, but I don’t think it was a factory
offering.</DIV>
<DIV> </DIV>
<DIV>The picture on David’s site is from one of the vtoldboys webpages <A

and is of a BBC machine taken in the late 90’s. My guess is that the
control panel was a BBC special product. It certainly is very different
from the several standard panels available from Ampex.</DIV>

<DIV>Perhaps Bill Carpenter will be the expert on this one.</DIV>
<DIV> </DIV>
<DIV>David Dean in Great Britain has an AVR 2 with the TRW A to D chip instead
of the original A to D boards. I also looked at the picture that he has on
line showing the machine. There was a different control panel
layout. see <A href="http://www.westpoint.tv">www.westpoint.tv</A> for the
pictures</DIV>
<DIV> </DIV>
<DIV>So when did Ampex change the A to D design to the TRW chip? How many
were made with this?</DIV>
<DIV> </DIV>
<DIV>When did the control panel change to place the meters on the left
side? </DIV>
<DIV> </DIV>
<DIV>I have seen pictures of a number of machines that have the deck tilted at
an angle. Was this an Ampex option or did this become standard on later
machines?</DIV>
<DIV> </DIV>
<DIV>Or are these things making this a one off machine?</DIV>
