Styled very much like it's primary competitor, the Edison Standard, the AT was one of Columbia's most popular machine. | |
Unlike the Edison machines, which had their feedscreews exposed, or very simple covered, the AT's feed screw is carefully protected inside the reproducer carriage arm. | |
The Trunion (the reproducer support arm) placed the floating reproducer in a nearly horizontal position over the cylinder. This allows the full weight of the reproducer to ride the recoding, enhancing the volume. |
