Note :
Portions of the circuit contained within 
the marked areas as shown have high 
voltages present. Use care to prevent 
electric shock during inspection or repair.
An Isolation Transformer must be used
during any Service work to avoid possible
shock hazard due to live chassis. The 
chassis of this receiver is directly 
connected to the power line.
