The old standby in hundreds of TV repair shops across the country. It containes a flying spot scanner to generate test patterns on the tv being serviced. The 1076 utilizes two output tubes. One of these tubes drives the CRT deflection coils and flyback for the flying spot scanner, the other is used as a vertical or horizontal plate driver. This allows the user to actually substitute the 1076's drive in place of the drive in a faulty receiver. Other signal and voltage sources include: calibrated -25 to +25 volt bias voltages; -50 to +50 ssync signals; composite video signal; 4.5MHz audio IF carrier; 400Hz audio tone; any IF frequency between 20 and 48MHz; RF outputs to channels 2-8, 12, and 13; AGC keying pulse; HV indicator probe; Boost B+ indicator; and a flyback/yoke tester that will detect shorted turns.
