Additional Details

Description

The EM-1 Newscaster was an early portable recorder using a spring-powered motor.
It was designed for rugged and dependable operation in remote locations where power wasn’t available. The governor-controlled spring motor mechanism assured constant speed and precise accuracy impossible to maintain with battery operated motors of the era.
Five minutes of operation was all it gave on a single winding, but the motor could be rewound during operation without affecting tape speed or timing accuracy.
