Why did so many amps in the 80s use two STK ICs.
What advantage did they get ?. And over time I see this has moved towards using single STK ICs.
Example My akain amp has two STK ICs. One 3042 and one 2250
The STK AMP im building has one IC a STK4231.
Im thinking why not have two STKs in my new design and does the other IC have to be an STK or can I use some other Chip amp or even an op amp with the 4231.
Simple english on the why 2 STKs would help.
Some people call the two IC concept a differential setup. Some say its not. Some clarity on this point would help.
