If completereceiver alignment Is tohe performed, It can most conveniently be done In the orderoutlined.
If the picture tube is removed, it will be necessary to shortpins 1 and14ofthe picturetubesocket to complete the filament circuit.
Use an isolationtransformer to protect the test equipment.

Check all high band channels for response
curve similar toFig5. Note the possible
variation. If necessaryslightlyexpand or
compress L4 to obtainproper response on
channel 13.It IA is adjustedrepeat steps
11 and12.
Expand or compressturns of antenna
coil (A16) to place 83. 25MC marker as shown
in Fig6. Adjust RF coil turns (A17) to
place 87. 75MC marker as shown in Fig. 6.
Adjust collturns to placemarkers as shown
in Fig6, making sure the antennacoil is
