The KI got a copper plated chassis and toroidial transformer. Several capacitors are different as well.

The copper plating should provide a better shielding and a maybe larger effect is the better/more stable ground potential.

Sorry I was a bit inaccurate in my question.
I know the outfit difference, there is missing tone controls.

But I'd like to know how the schema differs?

The copper plate chassis may actually bring difference because the gnd of the loudspeaker erminals is connected to power amd input only via chassis.

The basic circuit is the same but some part value were changed. Main elcos were custom made by ELNA other capacitors were exchanged by ones from other suppliers.
