If my memory serves, the RCA digital servo had a brake circuit in the headwheel motor driver that would stop the motor if air bearing pressure was lost.<br>

<div>Harold is correct if this is an air bearing head, and more importantly, it
can be seriously damaged by turning it without air.</div>
<div> </div>
<div>The nameplate will have an MI- number. Give us that number and we can
tell if it is air or ball bearing, 5 or 10 mil.</div>

The
headwheel will not turn freely without a source of air pressure. Maybe someone
on the list with an RCA machine could use
it.<br>

I had sent him the VR-2000 videos that Park had <br>
<br>
put up recently. He then brought me over to the engineering closet and showed me <br>
<br>
something I hadn't seen in around 20 years; a case with an RCA headwheel <br>
<br>
assembly.<br>
<br>
<br>
<br>
It looks fairly intact, but the motor doesn't spin freely. Probably too many <br>
<br>
years in the humid Florida weather. It had a sticker indicating that it had been <br>
<br>
refurbished by... (CVC??? I don't remember, the company owned by Kodak. I know I <br>
<br>
saw a lot of those labels before)<br>
<br>
<br>
<br>
Is it just an artifact to be admired, or should I implore the company to have it <br>
<br>
refurbished for some greater good?<br>
<br>
<br>
<br>
Anyway, it was fascinating to see one again.<br>
