All voltages are measured relative to ground with voltmeterfinner
resistance 10 Mohms).

Voltages are measured without signal in posotion FM.

Signal paths are shown for AM (position LW), FM, and forAF right
channel.

Mechanical switches are shown in neutral position.

CO-ORDINATE NUMBERS

The biggest PC boards are provided woth co-ordinate system. The
components on these PC boards are provided with a coordinate
number on the diagram (smaller printing type than the position
numbers) indicating in which coeordinate they are placed on the PC
board.

When replacing components with this symbol use the same type and
the same values for ohms and watts, The new components is to be
mounted in the same way as the replaced.
