<div><font size="3">Not certain about the VR-1000 but I have seen Mk-III heads
with the manual positioner installed although they could have been for the
1100.</font></div>

<div><font size="3">The guide servo was not available for the VR-1100.
</font><font size="3">As you point out, the manual positioner was available for
the Mk-X used on those machines, and in fact, the X was required for most of the
1100's beyond the early production units which used the Mk-III. All
later 1100's had an additional chassis with the individual channel
adjustments and included a label on the deck plate stating that a Mk-X head was
required.</font></div>
<div><font size="3"></font> </div>
<div><font size="3">The guide servo was an option on the VR-1200, although I've
not seen one without it except in catalog pictures. The 1200E does not
include a control on the operator panel, so I assume it was not offered and
certainly wasn't needed for recording. I suppose a studio machine used
only for recording would have no need for one either, so maybe some 1200's were
sold in that configuration.</font></div>
<div><font size="3"></font> </div>
<div><font size="3">There is however, a definitive way to determine if the head
shown in the pictures is a X or a XV. Only the machine-mounted head in the
next to last pic is a XV.</font></div>

<div>The first guess would be that the head has a manual guide adjuster on
it. This was on the Mark 15 heads. </div>
<div> </div>
<div>But there were some machines that may have not used the auto
guide assembly. I say this as the guide was listed as an accessory in
the set of books. </div>
<div> </div>
<div>So does anyone know if there was a machine that did not have the
electronic guide assembly in the VR-1000, 1100, or 1200 series. How
about the E models that were the low boy so called portable units? Or
the 1100's?</div>
<div> </div>
<div>Now Mark 10 heads could be used in earlier machines. There was a
trimmer module that replaced the nuvistor or transistor pre amp that allowed
this.</div>
