The the modern way of thinking that only tube power amps with ab output sections if even those, can and need to be biased has led to the idea that ss output sections arent biased at all, nor do they need the bias to be checked and adjusted. We can say that a transistor is the combination of two diodes it is a connected back to back. And also most of the distortion and overheating problems can be remedied by just adjusting the said bias.
