[QuadList] RCA Headwheel

 Hello again,

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.

Harold is correct if this is an air bearing head, and more importantly, it can be seriously damaged by turning it without air.
 
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.

Scott,

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

Regards,
Harold

I was talking to our CE today. I had sent him the VR-2000 videos that Park had 

put up recently. He then brought me over to the engineering closet and showed me 

something I hadn't seen in around 20 years; a case with an RCA headwheel 

assembly.



It looks fairly intact, but the motor doesn't spin freely. Probably too many 

years in the humid Florida weather. It had a sticker indicating that it had been 

refurbished by... (CVC??? I don't remember, the company owned by Kodak. I know I 

saw a lot of those labels before)



Is it just an artifact to be admired, or should I implore the company to have it 

refurbished for some greater good?



Anyway, it was fascinating to see one again.
