[QuadList] Ampex Mark Ten 10 mil head

[Don Norwood]

Hi Chris:

Yes, I have.  The results vary.  I have a Videomax BB rebuild that is almost as good as an Air Bearing.  The worst I've had was an Ampex, but still well within the correction range although I don't recall the exact amount of error.  Understandably, they can also get worse with age.

The VR-3000 uses only BB heads, and the quality of the recordings can be quite good.  I currently have a MK-11 head installed that doesn't sound good at all, but the performance is fine.

  Ball Bearing heads were used for years on the early machines.  I had no problem with them on the TRT-1 that I had.  It can have more error then an air bearing.  There is a sensor on the deck of the 1200 and other machines that will tell the machine that it has ball bearing head installed.  It would be interesting to see how bad the AMTEC error would be in this case.  Has anyone ever used a ball bearing head on the later machines?

  Be aware that this is a BALL Bearing head, NOT AN AIR BEARING. It is 10 mil according to the part number. 
   
  I see that the link to the specs goes to a page on my website, but I do not know the seller or anything else about this head.

  There is a second Ampex Mark Ten head on e-bay. Item number 400088699558, presumably 10 mil, since it does not have a "5 mil" sticker on it.
