Ampex Mark 10 Control Track R/P Head and Vacuum Hose Replacement
cache/wst.opf.4475040.xml
This project describes a fairly common problem with Ampex Mark 10 and Mark 15 video head assemblies. A way to replace a dried-out or decomposing sticky vacuum hose. A more uncommon problem is replacement of the Control Track R/P head. It does occasionally happen, most commonly the coil will become an open circuit internally. Interestingly, I have replaced more of the newer heads than the older type heads. All with the same trouble, an open head coil.
The replacement vacuum tubing is 1/8" ID surgical type. It can usually be found locally at many hardware or hobby stores.
It is also a good idea to have on hand a set of Bristol wrenches as the Ampex video head assemblies employ both Allen and Bristol types of machine screws.
