[QuadList] Ampex Quad VTR Airflow Requirements

[C. Park Seward]

Steve and Roger,

You have received some good info. I like the Gast units too. Expensive but quiet and works for a long time between overhauls. I'll send the manual for my model in another email.

Be sure to get a moisture filter.

Here is a page from Ampex talking about air requirements.



Best,
Park
