KSA50, KSA100 and KMA100 monoblocks there were ones with internal chimney heatsinks that were fan forced and had proper amount of Class-A on them into 8ohms, KSA50 had 50w the KSA, and KMA had 100w
The other later ones with external heatsinks were just high bias Class-A/B 10-20 or so watts. Then there were the Plateau (sliding) biased ones, that never sounded that go to me.
I dare say these rare monoblock ones had some decent amount Class-A bias on them.
