I’ve just finished a K4700 kit in a Crown DC-300A mk2
PSU is symetrical : +60Vdc GND -60Vdc
Stereo : 150w / channel
There’s a 0.uF cap across each output terminal.
From the manual I couldn’t understand if I need to use the output resistance (R23 - R26)
I don’t understand your question.
Could you clarify it a bit further?
