[QuadList] AMPEX MARK TEN HIGH-EFFICIENCY VIDEO HEAD IN CASE

[Don Norwood]

Hi Tony:

I confirmed that the module is a trimpot, which indicates use with either a VR-1000 or original 1100.  Of course that can be swapped out, but it still leaves the ball bearings.  Like Ted, I'm curious about the 7811 process, especially in light of the head configuration.

  I just checked our log book and we refurbished this head back in 1982....  Looks good as new... the 7811 process was an RCA type transformer conversion.

    Hi Chris.....

    You'll note that all of the parts this seller is offering are likely from a VR-1000.  The reel motor is definitely VR-1000, the capstan motor likely is (note the caps which are not used on Intersync systems), and the head is ball bearing.  Can't tell from the pics what module is installed, but most likely trim pot.  The head could also be used on a VR-1100 that hasn't been updated, but isn't useful for a 1200 or 2000.  The capstan can be used by removing the caps, but the point is it's likely quite old, and the belt could also be a problem.  Just thoughts for anyone looking at these for spares!

    Don
