IT could be a switch for Btl Mode Operation. This would explain only one wire from left Output via a resistor and a switch to the right input

This sounds like the only reasonable explanation! If it had something to do with grounding or feedback then the switch would've been a bit pointless.

To be honest I never knew that KSA could actually be bridged as Krell always had separate monoblock amps - the KMA's.

So now when the wire mystery is solved, can anyone tell me what to replace the old ROE's in the negative feedback loop with?
