 Ampex MR-70 Vacuum Tube
(Nuvistor) Studio Recorder 2

Ampex MR-70 2 1

     Another MR-70, this one is a two track. These are considered by many to be the best of the vacuum tube era. The exact number built is not known but Ampex lost a fortune on the ones they did sell. They were made under the engineering leadership of Rein Narma (Fairchild 670 & more), however, in an AES interview, Mr. Narma said his participation on the MR project was limited. These machines sound fantastic but require a lot of time and patience to bring to spec.
