Notes:
1: Description of the " FM IF Adjustment" is not carried on this
Speaker
Manual. It is because the IF coil in the FM front end section
terminal
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.
2: The parts in the FM front end section are prepared in a
complete unit, so you can' t obtain each part individually
