Oscilloscope Waveform Pattern

The* waveforms shown are as observed on the wide band oscilloscope with tlrs monitor turned to a reasonably strong signal and a normal picture. The voltages shown on each waveform are the approximate peak amplitudes. If the waveforms are observed on the oscilloscope with a poor high frequency response, the corner of the pulses will tend to be more rounded than those shown and the amplitude of any high frequency pulse will tend to be less.

Controls You May Not Touch

Basically, on the Electrohome monitor, you can move any control you want EXCEPT for the B1 control. This sets the power supply voltage (ideally at 120 VDC) and is located right behind VERTICAL HOLD. The 13 Electrohome DOES NOT have this control. It may also be wise not to move the VERTICAL LINEARITY since this distorts the picture and is hard to reset perfectly. If you do move it, turn on the Cross Hatch Test Pattern of your game and try to get the squares to the point where they are equal in...

Part No M05100316a011

When the cabinet access door s are secured in piace, the SAFETY INTERLOCK SWITCH plunger s are in a fuliy depressed condition. The game circuit can function normally. When any cabinet access door s are opened, the SAFETY INTERLOCK SWITCH plunger s are in a partially extended condition. This isolates the game circuit from the line voltage. To restore power to the game circuit with the access door s open, gently pull the SAFETY INTERLOCK SWITCH plunger s out to the fully extended condition. THIS...
