<P> </P>
<P>Hey, I got a question for anyone on the list concerning the MK XV, AVR-2:</P>
<P> </P>
<P>Why wasn't there a head blower installed on the AVR-2 to cool the head motor ?</P>
<P> </P>
<P>Was it just the fact there was no more space available, or did the MK XV head not need cooling?</P>
<P> </P>
<P>I notice the transport top does have two holes drilled for cooling where the blower hose would normally connect.</P>
<P> </P>
<P>Thanks,</P>

<DIV>Hi Chris:</DIV>
<DIV> </DIV>
<DIV>Nope, it's not the same head in all of the pictures. The only one that's a XV is the one mounted on the machine. The others are a Mk-X. As I said, there's a definitive way to identify the Mk-X and the Mk-XV. Hint.......anytime you can see either the top or the bottom of the baseplate, you can tell whether it's a X or a XV.</DIV>

<DIV>You have answered a few questions. The only thing is that one has to assume that it is the same head in all the pictures. </DIV>
<DIV><BR></DIV>
<DIV>I would agree that it is a 15 head because of the probability of any other is so small. But if the firing squad was cleaning the rifles and loading them as I was asked the question, I would not bet the life on it.<BR><BR>Chris Hill</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>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>
