Tilt Tab Service
Tilt Tab Lamp and Switch Dis-assembly/Assembly
Tilt tab lamps may be removed by giving them one quarter turn in the counter clockwise
direction (as viewed from the back). The tilt tab encoder board may need to be removed to access
lamps hidden by it. Replace the lamp by reversing the operation.
To service the switches, the tilt tab board must be removed from the organ by removing the
mounting screws. The pivot bar may be detached from the circuit board by removing the rivits.
The rivits are released by pressing its center pin (from the switch side). Once the rivits are re-
moved, the pivot bar may removed and finally the silicon rubber switches. Do not handle the
conducting surfaces. Do not clean with solvent based cleaners as the carbon paste may dissolve.
Water or freon based cleaners without lubricants may be used, however. The switches should
measure less than one thousand ohms on resistance.
