16. B+ BOOST INDICATOR. This indicates the presence of B+ Boost
in the receiver under test when plate drive from the Television
Analyst is used.
17. HI VOLTAGE INDICATOR. Indicates the presence of Hi Voltage
R.F. to the hi voltage rectifier plate.
18. PILOT LIGHT. Indicates that the Television Analyst is either
"On" or in the "Stand-by" position.
Auxiliary Controls
In addition to the main controls on the front panel of the Television Analyst
there are auxiliary controls located inside the instrument or on the rear of the
chassis. The inside controls are accessible by raising the cover of the Analyst.
The location of these controls are shown in Fig. 2. A duplicate of Figure 2 is
located inside of the cover of the Analyst.
1. AUDIO GAIN CONTROL. (Rear of chassis). This Audio Gain
Control is used to control the amount of input signal to the audio
modulator when using an external audio source. This control has
no effect when using the 400 cycle tone. The Off-Audio-Tone Switch
must be in the audio position.

2. AUDIO INPUT JACK. (Rear of chassis). External audio such as
a signal from an F.M. tuner, Tape Recorder, Microphone etc. can be
fed into this jack to 'modulate the F.M. oscillator.
3. SYNC LEVEL CONTROL. (R-121). This control sets the level of
sync signal present in the composite video signal.
4. COLOR OSCILLATOR TRIMMER. (C-114). This capacitor trims
the frequency of the color oscillator to the precise frequency required.
5. 4.5 MC OSCILLATOR ADJUST. (L401). This coil adjustment sets
the frequency of the internal 4.5 me F.M. oscillator.
6. WIDTH (L-2 located on the chassis between V-11 and V-12). This
width coil controls the width of the horizontal scan on the 5BKPV1
scanning tube. Increasing the scan on 5BKPV -1 scanning tube re­
duces the size of the reproduced picture on the Television Receiver.
