Figure 19. External power amplifier
The power amplifier feedback loop can
be broken (pinns 19 and 20) thus making it
possble to insert external power transistors
to increase the audio output power. This
enables with external power supply an out-
put power of several watts fed into 4 - 16 ohm
loudspeaker. See. fig. 19.
