Note:
All capacitors are in wF unless otherwise noted. pF: uuF
50WV or tess are not indicated except for electrolytics
and tantalums,
All resistors are in 9 and 1/,W or less unless otherwise
specified.
Power voltage is 9 V and fed with regulated dc power
supply from external power voltage jack.
Voltage and waveforms are dc with respect to ground
under no-signal conditions.
Voltages are taken with a VOM (50 kQ2/V).
Voltage variations may be noted due to normal produc-
tion tolerances.
