audio amplifier 60 W: main circuit
To start the sim the power switch (top right) has to be open!
and close later!
The input frequency I turn down to 1 Hz. Wait till the output voltage drops to 0 V. Now the input can be turned back to 1 kHz.

1 kHz, max 1 V source to simulate audio input. The LCR on the left to simulate an speaker.

Works well in real - not sure about the sim model here. In real there are one of those circuits for each channel.
T´s are BC546, BD140, BD139, TIP2955, TIP3055. No idea where to get their sim parameters.

Just got the source for the project: http://www.sound.westhost.com/project3a.htm

FPA S2.1 is the sim of the power supply
