  • Notes

  • Ampro Models 757 and 757-A Tape Recorders incorporate push button controls for the functions: Record, Fast Forward, Rewind, Play, Stop. Actual control is achieved by means of solenoid actuated mechanisms. The two models, 757 and 757-A, are mechanically and electrically alike. Model 757-A is is mounted in an extremely rugged case designed to protect the unit against rough handling encountered in heavy duty operation and Model 757 is housed in a leatherette covered case of suitable construction for home use. Models 757 and 757-A have two tape speeds, 3 3/4 and 7 1/2 inches per second. Changing speeds is accomplished by sliding the "Speed change Switch" to the desired position: Open-reel type, 3.75 ips & 7.5 ips tape speed.
