19. Depress "bell" .and "rep" tabs. Depress key and verify that
the bell sound repeats.
20. Lift "rep" tab and depress "sust" tab. Hit and release a key
and verify that bell decays slowly after the key is released.
21. Lift "rep" and "bell" tabs and depress "glide" tab. Verify
that keyboard voltage glides between any two notes and verify
that GLIDE slider varies glide rate.
22. Observe the voltage at A21. Using "tunc" control set this
voltage to 0 volts +_ 100 mv. Depress "one octave" tab and
A above middle G on the keyboard. Observe a sawtooth wave
at emitter of Q46. Adjust R16 for precisely 440 llz.
23. Cinch-Jones Six Pin Connector Test.
a. Verify that the voltage between Pin 1 5 2 is
+9.000 ^20 mv.
b. Verify that the voltage between Pin 3 5 2 is
-9.000 +200 mv,
c. Depress the "one octave" tab, depress low C on
the keyboard, and adjust "tune" control for
125 llz. Apply +900 volts to Pin 4 and
verify that the oscillator frequency is now
500 Hz +50 Hz.
d. Raise all tabs and depress the lowest key on
keyboard. Observe output of IC22. Apply
-3 volts to Pin 5. Waveform should read .8
volts pp. approximately. This tests the
external control of lowpass filter.
' e. Depress "bright" tab and second C from the bottom of
keyboard. Observe waveform at source of Q41.
Apply -3 volts to Pin 5. Waveform should compare
to waveform in Fig. 12. This tests the external
control of the bandpass filter.
f. Raise all tabs. Momentarily apply +9.00 volts to
Pin 6. Verify that a trigger occurs when the
voltage is applied.
24. Depress "bright" tab and any key on keyboard. Apply -3 volts
to Filter Control Jack. Verify that the harmonic content of
output waveform decreases. This determines whether Filter
Control Jack wiring is correct.
