The AP board as depicted in Figure 23 uses an external 15 volts power source, which is 
supplied through a DC input jack, located on the H Board. The Main switch, which is 
located on the K board, provides the switching of this power source to the AP Board. 
The main 9 volts, 3.3 volts, and 2.5 volts in addition to the sub 5 volts are used on the 
DG board. The 30 and 2.5 volts tuner voltages used by the B1 board are all derived 
from this board. The main 10.8 and sub 11.2 volts power the speaker and woofer amps.
