(Viewable by AES members.)


We see a visit to the Ampex headquarters in Redwood City, with an explanation of audio and instrumentation recording. Brief interviews with Bob Sackman (Instrumentation Div. Manager), Walt Selsted (Engineering and Research Div Manager), Phil Gundy (Audio Div Manager), George Long (Ampex President), and Alex Poniatoff (Ampex Founder), then a demonstration of making a “Sound-on-sound” recording.


Finally a review of manufacturing a Model 600 audio recorder: making heads (stacking laminations, lapping pole tips, winding the coil, assembling and testing the finished head), and making a wiring harness (with [the other] Charlie Anderson).
