FEBRUARY, 1932 Page 3 STOPS BOX-OFFICE REFUND! WESTON MODEL 564 • Recently ... a big Mid-western city ... a crowded House . . . middle of the evening show . . . suddenly the Sound went dead. • Frantic projectionists inspected connections, switches, tubes . . . two minutes . . . three . . . five. Impatient, the audience began to file out. Ticket refunds were demanded and given. Eight minutes . . . ten. Still no Sound. Then a hurry call for the manufacturer's service man. • Seven minutes later he arrived. His handy, portable Volt-ohmmeter went to work. In three minutes the show was on! The cause of the twenty-minute breakdown had been located and fixed . . . Another example of the importance and value of portable testing instruments in the projection booth. • The modern projection booth must be equipped with adequate portable testing instruments to prevent breakdowns— costly interruptions of performances. By checking circuits, tubes, batteries and other apparatus regularly, failure is anticipated, reproduction quality maintained — replacement or repair effected before failure occurs. Good instruments are insurance — your protection from breakdowns. • For this work Weston recommends Model 564 Voltohmmeter or Model 595 Sound Equipment Tester. Complete information about these instruments— vitally important in modern projection maintenance — will be gladly sent on request. WRITE TODAY!
