Note 2:
The stereo input signal is made by summing 123 mVrms LEFT or RIGHT modulated signal with 25 mVrms of 19 kHz pilot tone, measuring all voltages with
an average responding meter calibrated in rms. The resulting waveform is about 800 mVp-p.
Note 3:
For operation in ambient temperatures above 25

Note 4:
Measured with a stereo composite signal consistency of 80% stereo, 10% pilot and 10% SCA as defined in the FCC Rules on Broadcasting.
Note 5:
VCO ‘‘OFF’’ curve represents the distortion attainable using good 19 kHz and 38 kHz filters.
