Several identical amplifier+column sets that were gifts to friends.

Technical assumptions:

Input selector - in-A or in-B ;
Delayed speaker activation ;
Speaker quick disconnect after power failure / shutdown ;
Headphone output ;
Output selector working in A, B, A+B ( where A is speakers and B is headphones ) ;
Clear and easy to read display indicating the status of the device ;
Alarm mode in case of exceeding specified heatsink temperature (I did not use it after lowering supply voltage, although on the board there are appropriate connections for thermal switch);
